How to Recover Gold from Cell phones?



The cell phone has become an essential thing in our life today. We seem to be incomplete without cell phones. And it is a plus point for the E-waste recyclers. There is a great variation in the yields of precious metals from the cell phones of different makes. I mean, you don’t get the same amount of precious metals from all the cell phones. Branded mobile phones give you better gold recovery than the cheaper ones, especially, made in china. If you dismantle a cell phone, you will find the gold on its motherboard (PCB), the connectors in cell phones are gold plated. The chips on the mobile motherboard also have gold in them.
Before recovering gold from the cell phones, you have to dismantle them. The ceramic capacitors in the cell phones contain silver, gold, palladium and sometime platinum also. So, first of all remove all the components from the motherboards carefully. There are many videos on YouTube that explain the dismantling of cell phones. You can watch one or two videos and understand the whole process.
First, we will talk about gold recovery from mobile PCB. These days there are many non cyanide gold recovery chemical compounds with different brand names available in the market. You can search them on the net and buy one. They are very economical and most of them are made in China. Their brochures provide you complete details about how to use the chemicals for gold recovery. So, for gold recovery from mobile PCBs, you can use that chemical. Another option is cyanide gold recovery also. But cyanide is harmful. If you need some help about it. You can write to me also.
Secondly, we need to recover gold from gold plated connectors used in mobile phones. You can use nitric acid for it. Gold recovery from gold plated pins through nitric acid is also a good process. But you should do it in an open place or an appropriately ventilated room.
Thirdly, you have to process chips for gold recovery. Chips are first burnt, and then ground into a fine powder. Then the pins are separated from the powder/ash through a sieve. Store these pins, and when you have a saleable quantity of these pins, you can sell them to a smelter.
The fine ash contains the very thin gold wires used in bonding in the integrated circuits. So, you can wash away all the ash with water using a metal bowl. This method is known as panning. There are many companies who sell these panning bowls. They show you a demo also. It is not very expensive. You can get it at an affordable price. After removing the ash, you have silicon chips and golden wires left in the bowl. You can recycle that gold with aqua regia.
Apart from chips, there are other components also on the motherboard that contain gold. They can also be treated with aqua regia for gold recovery.
I have intentionally kept the article short. Mentioning all the details about gold recovery processes would make the article too long. And some people might find a long article boring. So, I have given the basic ideas about the processes mentioned above. You can always write to me, if you need to know more about any of the processes mentioned in the article. You can reach me through my website: www.recovercomputergold.com

For Current Computer Scrap Rates,

Is there any future for e-waste recycling in India?

E-waste recycling undoubtedly holds a great future in India. But you have to streamline this trade. Last year, 1.85 million tons of e-waste was generated in India.
We are all  increasingly getting addicted to a variety of electronic devices. So, obviously, every year the quantity of e-waste in India is going to be even more. India is marching towards prosperity at a faster pace. And this has given the Indian consumer a great power to buy good brands of mobiles and laptops, etc... Expensive brands use more precious metals in their gadgets. And, as a result, when recycling companies recycle precious metals from them, they make more profit.
Electronic scrap recycling is a metal business. Metal business has many advantages- it is a cash business. Any metal sells like hot cakes. Iron is the cheapest metal compared to copper and aluminum, etc.; you can even sell this metal any time on the phone. The reason being, every metal finds so many uses that its demand never decreases. There could be little timely fluctuation in the prices sometimes, but it does not affect the demand much. These factors plus many more make people opt for e-waste recycling business in India.
All the big companies just want to get rid of e-waste because they want their place clean. That’s why they dispose of their e-waste either at a very little price or free of any charge. Some of the workers of the big firms are very careless. They throw away the computer or just any other electronic device even with the slightest fault. And the recyclers benefit a great deal from this practice. When the recyclers pick up CPUs or monitors from big companies, they segregate them and have those machines tested and refurbished. Around 30 to 40 percent material, be it computers or mobile phones or just any other e-scrap becomes functional with slight repair. And, this way, recyclers make a lot of profit. And this will never stop.
Another important thing that goes in favour of the licensed recyclers is that the government has made a law that only licensed recyclers can pick up the material now, because 80% e-waste in India is processed in illegal/unauthorized sector. And the people in the unauthorized sector don’t use any machines to process it. They simply burn big piles of it in the open and create a lot of pollution. Until sometime back, it was a big problem for the authorized e-waste recyclers, because they had tough competition with the small scale illegal sector recyclers. But now, the government of India is very strict about the pollution issues. It is coming down very hard on the unauthorized sector. A lot of the raids are conducted in the illegal sector; the unbilled materials worth hundreds of millions of rupees are seized every month. Severe penalties are imposed. And this goes in favour of the registered recyclers. Because all these strict measures are taking the e-waste recycling industry towards an opportunity which the registered recyclers had long been waiting for. So, there is definitely a good future for e-waste recycling in India in an environment friendly manner.

Gold content in BGA chips

How much gold from one kilo of BGA chips? Well the answer is quite a lot. You get 7 grams of gold per kilo. But, here you have to be very careful about one particular thing. And that is that you get this yield from Intel BGA chips. If it is quite an old batch from Korea or Taiwan, you can get up to 3 grams of gold per kilo. But BGA chips from Chinese motherboards have a very low yield. You won’t believe you don’t even get half gram of gold from the current Chinese BGA chips per kilo. We get BGA chips from rams also. From those chips, we get around 3 grams of gold per kilo. Some rams have normal chips. Their current yield is 1.1 grams of gold per kilo.
In my next post, I will explain the process of gold recovery from BGA chips.

How to set up an E-waste Recycling Plant/Facility

Start electronic scrap recycling and get rich soon. This is one of the world’s best businesses these days because it is a metal business. You get gold, silver, palladium, platinum, copper, lead, tin, aluminum and so many rare metals from this.
First and foremost thing before starting a business is to look for the sources of the raw material at a very good price. And the best thing about this business is that e-waste generation is increasing by the day.
Second important factor is to decide the size of the plant, according to your budget. Third is the area of the land. And the fourth and most important aspect is the selection of the machinery. The best electronic scrap recycling machines are either from Germany or Italy. China also makes electronic waste recycling plants, but they are not as durable as that of Germany and Italy. Some Turkish companies also sell these plants. They too are not as satisfactory as their manufacturers claim them to be. So, do a thorough research before buying the electronic waste recycling machines.
After this comes the skilled chemists and engineers. Most of the plants fail just because their consultants, chemists, engineers and the management team as a whole lack expertise in the field.
Another important aspect to be kept in mind is that don’t start the facility right away. I mean to say, gain some experience first. You may either do a job in a recycling facility to understand the nature of the business completely or start the business on a small scale first. The benefits of this strategy are that you get to understand all the ups and downs of the business. You can even first start as a dismantler. Even if you have some loss, it will be very little in comparison to the one you might have by starting the plant without experience.
The secret I am going to reveal to you now is that inexperienced people are not able to decide what material to process and what not? Whereas experienced people only recycle the stuff that gives more profit. I receive so many calls from people in the process of setting up the e-waste recycling facility almost every week telling me their consultant has advised them to recycle computer motherboards only. And I pray to God for their mental equilibrium in the time to come.
So, it is undoubtedly a good business, yet you need to take into consideration so many aspects before starting an e-waste facility. This topic is very big, so I will keep providing you with very useful information on it in parts.
Hope you like the tips that I have given. It is the result of my thirty years of experience in this field.

Silver Recovery Raw Materials

How to recover silver/silver recovery process/silver extraction/x-ray film silver recovery
All these keywords used on different search engines indicate people’s quest for learning silver recovery process and make money. I receive a lot of phone calls and emails in which people ask me about the silver recovery process either from X-ray films or from fixer solution. It portrays that majority of people who are interested in the silver recovery process are of the opinion that there are only two things from which you can recover the silver. But it is not so. There is a long list of items from which you can recover silver and make money. I would like to mention a few of them.

Apart from x-ray films and fixer solution, you can also recover silver from Ultrasound films, Compact Discs, diodes (electronic components), silver coated connectors mostly used in electronic industry, silver coated wires, Mirrors, Mobile Tower Boxes, Electrical Contacts, silver plated bathroom accessories, Crockery, Silver Oxide Battery, Solar Panels and old coins etc.
The best thing about them is that they are available in good quantity. And you can start this business with little investment and make a living out of it. And it is quite easy to recover silver from them.
Some people find it hard to trust. But they don’t know the fact that half of the silver consumed every year finds use in industrial applications. So, the recycling of silver from such items is undoubtedly a profitable business.
For further assistance on this matter, you can write to me.

Recover Gold from Electronic Scrap

Gold Recovery from Electronic Scrap is a very lucrative business. But you must find out the right source to buy the material. Because there are two things when you start this business. Number one you should choose the right methods to recover all precious metals from electronic waste (E-Waste). Number two- you should be good at purchasing the material also. Being good at only one thing won’t help.
When we say electronic scrap, it is not one single big thing. It is a mixture of either, so many electronic circuit boards or a variety of whole devices. The best thing about it, according to my experience is that you should not process everything. You should be choosy if you want to make more money in a short time. When we talk about precious metal recovery from electronic scrap, it is not every component of the electronic scrap that yields precious metals. There are only particular components where precious metals are used. For example, chips, processors, golden fingers, gold plated connectors, some special diodes and transistors, monolithic ceramic capacitors  and relays etc..
If you happen to buy a mixed lot of electronic scrap, you should first segregate the items. Now one by one take away the above mentioned precious metal bearing components. There are customers for almost everything that you get from e-waste. So, you can sell the rest of the items (Non gold bearing ones) to the e-waste recyclers.
There are tests through which you can determine the presence of different precious metals. For example, if you think that a particular component is silver plated. You can first put a drop of nitric acid on it, and then a drop of hydrochloric acid. If there is silver, either in the form of alloy or polish; there will be curd- like formation on the surface of the metal. For gold, you can put a drop of nitric acid on a component or a piece of metal looking like gold. Gold does not react with nitric acid. It stays as it is. If it is copper or brass etc., nitric acid will react and dissolve the metal. The same way, there are methods for testing palladium and platinum also.
Gold polish can be removed from the components through an AP process. CPU’s/Processors are best treated for gold recovery with aqua regia. Gold can be removed from the pins through sulfuric cell also.
In my next article, we will discuss some precious metal recovery methods in detail.

Please follow, share and like my blog, and oblige me with your comments if you like this article. 
Thanks for your time!


CPU-Processor Gold Recovery

CPU Gold Recovery can be done through many ways. Some people crush the whole CPU into powder and then separate the metals from the powder through density separation. But in my opinion, this is not the best way, because you have a precious metals loss in it. CPU's contain gold, palladium and silver, etc. people normally think that you get only gold from the processors. It is not true. If you look at them  closely, you will see MLCCs on them. MLCCs (Monolithic Ceramic Capacitors) contain palladium, silver and gold.
So, the best gold recovery method from CPU’s/Processors is to recover gold through aqua regia. You should first remove MLCCs from the processors and store these small capacitors safely for silver, gold and palladium recovery in future when they are in enough quantity. Now break the processors into smaller pieces by some hammer. Prepare the aqua regia solution. The aqua regia solution is one part nitric acid and three parts hydrochloric acid. You should use heat resistant glass pot for it. First put the broken processors into the pot and now pour some aqua regia into the pot. The reaction will start and the solution will start eating pins etc. including gold. Do it in an open space or a properly ventilated room and use safety gear.
Separate the solution from the solids after the reaction has stopped completely. Now you need to neutralize this gold bearing aqua regia solution. And, for this, you may use urea. Add some urea to the solution, and there will be a lot of fizzing. There will be lots of foam. After some time, the foams will disappear. Now, again add some more urea to the solution. The foams will form on the surface and subside quickly. Keep repeating it till foams start taking longer time to subside. Stop adding urea to the solution, when foams take too long to subside. Now your solution is neutralized. Filter this solution and recover your gold with sodium metabisulfite (SMB)

How to Recover Silver from Silver Nitrate Solution?

When silver reacts with nitric acid (HNO3) silver nitrate is formed. It is very easy to recover silver metal from silver nitrate (AgNo3). First filter the silver nitrate solution, so that all the unwanted material is removed from it and we get a better quality of silver. Take a plastic pot and pour all the silver nitrate into it. Now start adding HCL (Hydrochloric Acid) to it in small increments. The moment you add HCL to silver nitrate solution, silver starts separating from it in the form of silver chloride. Keep adding HCL to the solution till there is no more silver separating from silver nitrate solution.

Silver chloride (AgCl) is a curd like silver compound in appearance. It precipitates immediately. Give it around half an hour to settle to the bottom completely. Heavier particles settle immediately and lighter ones take some time to go to the bottom. After that, separate the liquid from the silver chloride by tilting the pot. Wash the silver chloride with plain water at least twice. Now dissolve some glucose into the plain water and keep it in a plastic can. Add some quantity of this glucose water to silver chloride. And stir around the silver chloride with some glass rod. Silver chloride will start converting to metallic silver. Keep doing it slowly till all the silver chloride has changed into silver. Now put this silver onto a filter paper or filter cloth so that all the water should filter out of it. You can leave it for a night. By the morning, there will be no or little moisture left in the silver. You can dry it on a lighter flame in a glass pot and melt it.

How to Recover Gold from GPC Solution Tutorial?

Gold recovery from GPC (Gold Potassium Cyanide) solution is a very profitable business. I am going to give you a very easy process for gold recovery from gold potassium cyanide solution. Gold can be easily recovered from this solution with zinc dust. It is a metal displacement theory.
Heat the solution to around 60 degrees Celsius. You may either use a PVC/Plastic or glass container for it. You can use a glass heater for heating the solution.  Add five to ten grams of (325 mesh) zinc dust per liter. Stir the solution with a glass rod for about five minutes at least five times with a gap of one hour (each time). Leave the solution for a night. But make sure the solution should remain hot throughout the night. Zinc dust will displace all the gold from the solution by the morning. Pour out all the liquid into another container, leaving behind the gold dust.
This gold dust has some zinc impurity in it. So, it needs to be refined. For this, you treat it either with dilute sulfuric or nitric acid for five to ten minutes on a lighter flame. This treatment will produce some smoke. So, use a properly ventilated place for it. During the reaction, bubbles come to the surface and break and give out smoke of green color. It is an indication of the zinc dust being dissolved into the acid. When the gold dust is refined, the bubbles and green smoke stop completely. Wash this refined gold dust with water three to four times. Dry and melt it into a gold button.

Note: I have uploaded a video regarding it on my YouTube channel: https://www.youtube.com/user/uroojmetals
The comments and mails that I receive from people suggest that I am talking about producing GPC (Gold Potassium Cyanide) solution for gold recovery. It is not that. GPC is used in gold plating different materials such as artificial jewelry water taps, door handles and many more things. Some companies don’t recover gold from the spent up cyanide solutions. They prefer to sell it to the outsiders. So, this video is for those who want to make money through GPC by purchasing it from the gold plating plants. You can really make a lot of money by recovering gold from this exhausted GPC solution. Please use safety gear if you do this process.

How to buy BGA Chips & make more money from them?

You can make a lot of money by recovering gold from BGA chips. It is very easy to recover gold from them. But you must be very careful about purchasing this material Just because the BGA chips from Chinese computer mother boards have as low as one gram of gold per kilo or even less. I remember, some ten to fifteen years back, BGA chips had a yield of 7 grams of gold per kilo. But the important thing about that was that they were all of Intel make. The Intel mother boards from which they were removed were heavier in weight than the non Intel computer mother boards. BGA chips from AMD computer mother boards also had good yield of gold. With the passage of time, more and more companies started manufacturing mother boards and the competition became fierce. Price of gold also soared. As a result, gold content in BGA chips reduced.
It is not that we get BGA chips only from computer motherboards; we get them from many other sources also. We get BGA chips from hard drive logic cards, electronic devices used in telephone exchange or mobile towers etc.
If you want to recover gold from BGA chips, make sure you do a sample first, if it is a mixed lot of different makes. Buy a small quantity of it. Try to check the percentage of Intel chips in that lot. Intel chips will yield 7 grams of gold per kilo and the rest will give you one gram per kilo. So, assess the price of the lot, according to the ratio of the chips. You can even buy hard drives in a big quantity and dismantle them. As mentioned above chips mounted on the logic card in hard drives have higher gold value. You can recover gold from drives and sell the rest of the material to a metal trader. And, this way you can make more money from chips. Another way to make more money from chips is that always buy the old stuff manufactured in the year of 2002 or even before. We still get old stuff though not very much.
By following the above mentioned tips, you can certainly make more money from BGA chips.

Non aqua regia method for gold recovery from chips instantly

A lot of people around the world want quick and easy gold recovery from gold coated/polished computer parts scrap or other electronic waste. Some people even want to recover gold from scrap watches and their chains. And some want to recover gold from artificial jewelry. So guys, we have prepared a very effective gold removing solution. It recovers the gold from gold plated items instantly. We have also uploaded a video on YouTube about it. The URL is: https://youtu.be/smwPFjvR0RA
This solution is very economical. One time prepared solution works for five batches. If you want to know more about it, you can write to us by visiting our website: www.recovercomputergold.com
This solution does not attack copper if the material is taken out of it in a short time. But if the gold coated copper material remains in the solution for a longer period of time, it attacks copper mildly.
Some people use aqua regia for gold recovery. But you can’t recover gold through aqua regia from so many materials. For example, if you try to recover gold from gold plated stainless steel, aluminum or copper etc., using royal water, you will have to face great difficulty. Aqua regia will dissolve the above mentioned metals also. It will increase your processing cost, and precipitating the gold from AR solution will be very difficult. So, we carried out an intensive research and prepared an instant gold recovery solution. All you guys were looking for a solution that should dissolve the gold quickly and not attack the substrates.

There you go!

Note: People want to know the composition of the solution that I have used in gold recovery from chips in my video on my YouTube channel: https://youtu.be/smwPFjvR0RA   some people have sent me comments talking about their ideas that I have used Potassium Cyanide in my solution. This is not correct. These days there are many new combinations used for gold recovery from gold coated material. Even some gold miners are using those chemicals. Some Chinese companies are also selling such products that can easily recover gold from ores and other things. So, whatever opinions my friends expressed on my channels about the composition of the solution are not correct. It is a result of many years hard work. This video is edited. To know more about it, you may send us emails through our website: www.recovercomputergold.com

Gold and other Precious Metals recovery from Computer Parts/E-waste

Gold and other precious metal recovery from e-waste is a profitable business. Everybody is interested in gold and silver recovery from processors, rams, chips and hard drive, etc. Some people are interested even in medium scale e-waste recycling plants. It is undoubtedly a good business. But as we all know that Rome was not built within a day. The same applies to this business also. I find a lot of people on net promising huge profits with small investments in a very short time. And that makes me laugh like anything. They are all false claims. Beware of those people! But yes, one thing about this business is very positive and that is that it can be started with as little investment as 3000 to 5000 USD and you can easily make 20 to 25% profit on that. And you can process the material in two to three days. You get back your original amount with profit. And, then again, you can purchase the material and process it in a few days only. And this way, you can make more money in a month. I have been guiding people for more than thirty years about this line. If you keep patience, you can make quite a good amount of money in one or two years. Initially, you will have to do it manually, but once you are established, you can go for some low cost machines and expand your business.
The availability of raw material is not a problem. There are many ways to procure it. You should also keep one thing in mind that you should not purchase and process all kinds of material. You should process selected items only if you want to make more money safely.

How to Recover Silver from Electrical Silver Contacts?

Silver contacts are either made of pure silver and are soldered on copper strips or copper contacts are coated with a thick layer of silver. In both the conditions silver can be recovered with nitric acid (HNO3).
If the silver contacts are soldered on copper strips, you can cut the copper strips with a cutter to separate silver contacts from them. Now put all the silver contact points into a stainless steel pot. Take one part of nitric acid (68%) and one part of water and mix them together. Now pour this dilute nitric acid in small quantities onto the silver points in the stainless steel pot. The copper and silver will react with nitric acid and start dissolving into it. This reaction produces some smoke. So, either you should do it in the open or in a room with exhaust fan, so that the exhaust fan should send all the smoke out into the air. Keep pouring dilute nitric acid into the pot till all the metals dissolve into the solution. Now there are two metals in the solution in the form of nitrates that is- Silver nitrate and copper nitrate. First, we will recover silver from this solution. To do that, take HCL (Hydrochloric acid) 35% purity. Mix HCL with silver nitrate solution in small increments. Stop adding HCL to the solution when silver chloride stops separating from the solution. Decant the solution when silver chloride (AgCl) has settled down to the bottom completely.

Heat up some water and add it to the silver chloride. You can use a plastic pot for it. Take round iron pieces of around two inch diameter and half inch thickness. Put these iron rings onto silver chloride in plastic container. Slowly move around these iron rings for some time with a wooden rod. Silver chloride will start changing color and converting into pure silver. Stop stirring the rings when there is no silver chloride left in the container. Now you have got pure silver dust. Take out the rings; wash the silver dust with plain water three times. Dry this dust, and melt it into a solid piece of silver.
