How to recover silver and gold from computer parts, ewaste, chips, CPU, xray films, photographic waste, aqua regia, cyanide solution, circuit boards and RAMS. Recovery methods extract or recycle of precious metal like Palladium, Silver and Gold.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
Computer motherboard and other electronic circuit boards can also contain rich gold content made up of goldplated circuit traces, edge fingers, connectors, Integrated Circuits, transistors, amp; memory chips. There is very little profit from extracting the gold content found in most computer chips and electronic components yourself unless you
Jun 28, 2020#0183;#32;Subject some circuit boards to an acid treatment to release its materials and this stuff will gather up all the dissolved gold. And after it lets go of that gold, its ready to be used again.
Aug 31, 2016#0183;#32;While removing the gold locked in electronics has heretofore been a toxic and inefficient proposition, researchers now think that a new process will make prospecting for the precious metals in
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
The increase in gold extraction can be attributed to increases in residual Cu (II) in solution with increasing pH value resulting from the increase in free NH 3 ( Senanayake, 2004a,b ). Leaching at a higher pH value can also be beneficial in improving silver extraction and stabilizing silver in solution.

Mar 28, 2017#0183;#32;Gold, silver, platinum and palladium can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics. Although it is possible to melt the gold plating away from the circuitry, you will cause more of a mess and lose some of the precious metal.
The precious metal is a component within the circuit boards of mobile phones. Extracting gold from mobile phones is not a new phenomenon, and companies have been doing it for years.
