Electrolytic gold recovery and separation process ...

The recovery of gold from its ores is commonly accomplished by one of a number of methods including flotation, amalgamation with mercury or by the cyanide process. Where the gold content of the ore is high, smelting is economical; the cyanide process is employed for the lower concentrations of gold. ... By electrolysis, the active or nascent ...

Copper and gold recovery from CPU sockets by one-step ...

2019-3-10  Gold mainly exits in the electrolyte, and little gold can be electrodeposited. Besides, the results of XRD and SEM show that the obtained metal powder is mainly copper and copper powder particles are mainly dendritic. On the basis of these results, slurry electrolysis could be applied to the recovery of copper and gold from electronic component.

Electrochemical recovery of minor concentrations of gold ...

2018-6-10  Gold recovery and energy consumption. The recovery of gold and copper in validation tests L1 and L2 was quantified by dissolving the WE samples in concentrated aqua regia (HCl:HNO 3 = 3:1) and assaying the produced solution for Au and Cu with ICP-MS . As the material of working electrodes also contains traces of gold and copper, the chemical ...

Extraction of Gold

The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanide-process The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being ...
