Gold Recovery from Motherboards Computers & Laptops | Recycle Electronic Devices for Gold | Gold Recovery from Chips

Recycling motherboards is a profitable business. We have gold-plated connectors, monolithic ceramic capacitors, tantalum capacitors, copper transistors, aluminium condensers, aluminium heat sinks, normal chips, BGA chips, solder, brass pins, etc. on motherboards. We get gold, silver, palladium, tantalum, brass, copper, iron, solder (an alloy of tin and lead), and nickel from motherboards. First of all, we need to remove all the components from the motherboards. We accomplish this by circulating hot air through a motor-driven, perforated drum. All the components are segregated after their removal from the PCBs. There are two types of chips on motherboards: normal chips and BGA chips. BGA chips (which Intel and AMD make) contain 6.5 to 7 grammes of gold. Normal chips are of two types: PQFP and PLCC packages. PQFP chips contain 1.25 to 1.5 grammes of gold per kilo. PLCC chips contain 700 to 800 milligrammes of gold per kilo. Gold-plated connectors have 25 to 100 milligrammes of gold on them. The depopulation process removes the solder from the PCBs. Different processes, such as cyanidation, electrolysis, cupellation, and chemical leaching, are used to recover gold and other precious metals from the segregated components.

Gold Recovery from Sim Cards Cell Phones | Sim Cards Cell Phones Recycling for Gold | Gold Recovery

It is quite easy to recover gold from cell phones' SIM cards. You need to burn them first. But be careful; do it in an open space because burning SIM cards will produce a lot of smoke. You can get rid of that smoke if you burn them in an oven. And make sure that you burn each and every SIM card if you want 100 percent gold recovery out of them. Once the burning process is complete, allow it to cool for approximately 30 minutes. Now prepare the Aqua Regia solution: nitric acid in one part and hydrochloric acid in three parts. Stir the solution with a glass rod. Use only heat-resistant glass beakers for this. Put all your burnt stuff into the beaker first, and then pour AR solution onto it according to the requirement. There will be a strong reaction in the beaker. Because the metals, including gold, will dissolve in the AR solution. Keep away from the beaker for a while because the reaction produces harmful fumes. It's better if you do it under a fumehood. Stir the material in the solution until it completely dissolves all the metals. Leave it for about an hour. Filter the solution and neutralise it with urea. Sodium metabisulfite is used to precipitate the gold. If you have an inquiry about something, you can write to us using the contact form available on our blog.

How to Recover Gold from Cell Phone Motherboard Chips | Gold Recovery | Recycling E-waste

I have seen videos of people removing components from cell phones' motherboards and other types of electronic circuit boards with the help of a chisel and hammer. That's so much time-consuming, and you can't process bulk quantity through this method. if you are serious about this business and want to progress fast, you must first understand its nature. Until some years ago the profit margin was high, but now it is only up to 15% on a small scale. Because so many people are attracted to this line on account of gold and other precious metals recovery. And so, the competition is increasing day by day. So, your profit depends on careful purchasing of the raw material and its processing cost. As for removing the components from the circuit boards, you may use a solder-stripper. These days we can easily get a solder stripper in the market that doesn't attack other metals such as copper and nickel etc. It is available at an affordable price. You can prepare the solder-stripper yourself also. So, for gold recovery, you first need to remove the components with a solder stripper. These circuit boards contain precious metals such as gold, silver, and palladium, etc.., but in this article, we will discuss gold extraction only. For this, first of all, we need to burn the chips in an environmentally friendly way. The chips are ground into a fine powder after burning. And in the third step, metal is separated from the ash using a sieve. There are many ways to recover gold from the separated metals, but I would like to mention only two processes here. In the first method gold is leached with chemicals and then refined. Another method is to melt the metals into an ingot and recover gold through electrolysis. The second part of this article will deal with the recovery of metals such as silver and palladium. You can write to us through the contact form available on our blog If you want to learn the gold extraction process in detail. Warning!
