: 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.
Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the goldplated metal parts in the circuit boards using a magnet. Some goldplated parts may be inside ceramic components. Put on the goggles and gloves. Place all of the recovered circuit parts in one of the glass containers.
May 20, 2013· Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore. You get gold.

I am currently separating and extracting gold from margin ore dump (Mod) using the following processes: leaching, carbon in pulp, elution (zadra process) and electro winning. My final product (sludge gold) is contaminated with excessive copper. What method should I apply in order to make sure t
A printed circuit board contains metals such as copper, tin, silver, and lead along with minute quantities of gold. There are several methods that are used practically to extract gold from a printed circuit board. But before we can start the process we need to determine the amount of gold that the PCB contains.
Jul 11, 2019· My answer is to getting the gold free of copper, and it works for any alloy. 1. Raise the surface area/volume. Beat it until it is as thin as possible, or crush it and do your best to make dust/tiny fragments. 2. Put the whole of the sample into a...

Elecrowinning is in the meantime a frequently used process whereby gold is extracted without the use of toxic substances. This method uses an electrochemical approach. Here advantage is taken during the extraction of other precious metals such as copper or zinc where also small quantities of gold are found in the extracted rock.
Talking about recovering it is not going to be that easy. It is because there is not one extraction methodology that can be used to recover gold from different parts of computers. For different parts there is different recovering procedure. Like nitric process or CN process is used to extract gold from gold plating, polished pins and connectors.
