Q.1 : How to recover/ extract gold from computer parts ?
Ans. : Computer parts like processors (CPUs), RAMs, motherboards, hard drives, CD/DVD drives have gold and other precious metals like silver palladium etc. Base metals like copper, brass (an alloy), tin, aluminium, lead etc. are also present there.
SMPS (power supply), keyboard, cpu-fan doesn’t have gold but there is some silver in keyboards.
CPUs have gold and plating on its pins and gold wires inside them.
RAMs have gold plating on its fingers and gold wires inside the chips (QFP & PLCC) which are mounted on RAMs. There is palladium also in ceremic capacitors mounted on RAMs. There is some silver also in QFP and PLCC chips on RAMs.
In motherboards there is gold plating on different types of socket pins. There are BGA, QFP and PLCC chips mounted on motherboards, they all have enough gold and some silver in them.
Now talk about the recovery. Only one gold extraction method cannot be used to recover gold from all parts of computer. Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors. From CPUs we can recover gold through aqua regia.
Pyrolysis and hydrometallurgy are used for gold recovery from computer chips.
Our methods of gold recovery from computer parts are 100% safe and environment friendly. They are quite economical and less time consuming as well as easy to learn.
You may contact us for more details.
Q.2 : How to recover/ extract gold from motherboards ?
Ans. : Motherboard has precious metals like gold, silver, palladium etc. There are also base metals like copper, brass (an alloy), tin, aluminium etc. ; which can be recovered from motherboard to get even more profit. For gold recovery from motherboards CN process, aqua regia, nitric process, pyrolysis & hydrometallurgy can be used.

Q.3 : How to recover / extract gold from CN solution ?
Ans. : When we talk about CN process people think that CN process is used for gold recovery only. But my friends I want to tell you that CN process can be applied for silver recovery also. When we treat any gold or silver stuff with CN solution, it make gold CN (AuCN) and silver CN (AgCN). Gold and silver can be recovered from CN solution chemically as well as electrically.
To know more about CN process read our article “Recovery Methods”. To have complete knowledge and consultancy, you can choose suitable package at the payment page. For any queries contact us at email@example.com.
Q.4 : How to recover/extract gold from mobile phones ?
Ans. : 43% of total production of gold in the whole world is used in electronics. Can’t believe? But its true. And its also true that cell phones have big quantity of gold in them.If you open a cell phone, you can see gold plated connectors and pins. If you look at its motherboard, you will know that it is gold plated. Mobile motherboards have silver and palladium also. Ceramic capacitors used in cell phones have palladium. Chips mounted on cell phone motherboards have good quantity of gold and some silver also. To recover gold, silver and palladium from cell phones we first need to sink them in the chemical to remove the components. Doing so, we will get 1.gold plateds items, 2.ceramic capacitors, 3.chips.
Now we use CN process, nitric process, cupellation process, pyrolysis and hydrometallurgy to get pure gold, silver and palladium.
Q.5 : How to recover gold from aqua regia ?
Ans. : Many people come to us with this question. Before answering this question, I would like to tell you that aqua regia is not the only method to recover gold from electronic scrap. It is only one of the methods. If you want to use aqua regia to recover gold from electronic waste, you should first know that where and when you should appy AR method.
To recover gold from computer CPUs, aqua regia is the best method. Because CPUs have gold wires in them and there is no base metal present inside the CPUs.
To make aqua regia we have to mix 3 parts hydrochloric acid and 1 part nitric acid.
Read our article “Recovery Methods” to know more about aqua regia method.
If you want us to assist you for recovering gold through aqua regia method please write us at firstname.lastname@example.org.
Q.6 : How to recover gold from CPUs ?
Ans. : There are many methods which can be used to recover gold from CPUs, but aqua regia is the best method for it. Use nitric process or CN process to recover gold from green fiber CPUs. To know more about gold recovery from CPUs, read our article "Recovery Methods".

Q.7 : How to to recover / extract silver from x-ray films ?
Ans. : Before starting this business we must know the quantity of silver in 1 Kg. X-Ray films.
1 Kg. X-Ray films may have 3 to 8 grams silver. Used bone X-Ray films have more silver than chest X-Ray films. But if we buy scrap X-Ray films we get the mixed stuff. We do not advice to buy X-Ray film scrap from scrap dealers. Its better to buy directly from hospitals and labs. Because digital X-Ray films have no silver in them. If you buy from scrap dealers, you may get some digital X-Ray films also which have no silver and you may be at loss. Generally if you buy used X-Ray and Ultrasound films from hospitals or labs, You will get 5-6 grams silver recovery from 1 Kg.
Now we will talk about the silver recovery methods from X-Ray and ultrasound films. To recover silver from X-Ray films more than one methods can be used. In India some people use hot water & toxic chemicals to recover silver from X-Ray films, its a time consuming process and produces pollution.
We have developed some very good economical, less time consuming, easy and pollution free methods for silver recovery from X-Ray films.

Q.8 : How to recover silver from e-waste ?
Ans. : Silver is widely used in electronics and photographic industry. Many electronic and electric components have silver coating and silver points in them.
X-ray films have silver coating on them. Silver goes in fixer and hypo solutions when used in developing X-Rays and photographic films, which can be recovered from exhausted fixer and hypo solutions by using different methods.
If we talk about silver recovery from e-waste, some electric wires and good quality switches have silver coating and silver points also. Electronic component Relays (used in UPS, Stabilizer, Inverter etc.) have silver points, Ics and chips have silver, small transistors have big quantity of silver in them.
Anyone who wants to learn silver recovery from any types of e-waste may contact us. We will guide you completely to recover silver from e-waste, X-Rays and Ultrasound films, photographic waste and any silver solutions like hypo and fixer solutions.

Q.9 : How to recover gold from chips ?
Ans. : Electronic chips used in computers, cell phones and other electronic items have some silver also along with gold. You can recover both silver and gold by using our methods. To start the process you hav to burn them in an iron pot with zero pollution (smoke can be dissolved in chemical solutions). Then grind them into fine powder. This fine powder containing ash, gold, silver, copper, nickel etc. will be now melted using 3 chemicals including borax. After melting it you will get solid mixed metals gold, silver, copper, nickel etc. These metals can be seperated in the next step.
