Apr 26, 2017· Gold Recovery from Rams: Introduction: Gold recovery from ram is a very important part of computer recycling. Every Ewaste refiner wants to recycle it because it has a good quantity of gold, palladium, and silver. Ram''s recycling is not very complicated. The main reason for this tutorial is that many people want to know how much gold in them.
Total Recovery of Gold Contained in Computer Printed Circuit Boards. Leaching Kinetics of Cu, Zn and Ni 145 In this work, we propose to recover the gold contained in the printed circuit boards by means of acid dynamic leaching
Start by reducing the size of gold to smaller. Melt gold, pour gold while melting through a 2 mm sieve into the water. Reducing the size of gold to smaller Will help in the process of aqua regia to make gold into the solution more quickly. aqua regia is composed of 2 chemical substances, 1 nitric acid, 3 hydrochloric acid mixed together.
Gold Plated PCB''s (Military Grade PCB''s, Vintage PCB''s, Communication Equipment PCB''s, Cell Phone PCB''s) Depending on plating coverage, quantity of conductive layers, application and recovery method may yield between g of gold per lb. Military and Communication equipment PCB''s will yield the highest amount of gold.
In another technique, sulfuric acid dissolves the ceramic honeycomb, leaving behind the platinum. The ceramic can also be volatized, or turned into a gas or liquid, a process that would leave behind the platinum. Platinum recovery from catalytic converters and electronics components is a much more expensive and difficult process than gold recovery.
The common processes for recovery of gold solution includes: (i) Carbon adsorption, MerrillCrowe process, (iii) electrowinning and (iv) ionexchange / solvent extraction. Traditionally, MerrillCrowe process was used to remove gold from a cyanide solution by using zinc dust to precipitate gold .
