copper mining gold separation process

Separating Copper from Gold (electroplating ...

There is a process to remove copper from carbon prior to stripping gold called a "cold cyanide strip". I think it will be difficult to remove Cu from Au in the electrolyte solution. You can find it the paper on Onemine. It is called "Control of Copper in Carbon Adsorption and Gold Recovery Circuits - American Girl Mining Experience" dated 1993 authored by C. L. McKenzie.

Gold extraction - Wikipedia

Mercury is a health hazard, especially when in gas form. To remove this hazard, before smelting, gold precipitates from electrowinning or Merrill–Crowe processes are usually heated in a retort to recover any mercury present, that would otherwise cause health and environmental problems due to its release (volatilization) during smelting. The mercury present is not usually from the mercury amalgamationprocess that is no longer used by formal gold mining companies, but from mercury in the ore that has followed g

11/12/2015  Microbial leaching process used in gold separation. Microbial leaching process is usually used in the ore with low quality of gold and in the mine with large stone capacity. The sulfur mine such as iron sulfide in the ore wraps the gold which prevents the reaction between the cyanide leaching and gold ore. Before leaching, the microorganism, such as ferrooxidans, will be used to resolve the sulfur mine

11/10/2015  When the cuprocyanide has dissolved its maximum of copper, part of the copper in the solution is precipitated electrolytically during which a partial regeneration of the cyanide is said to take place. The treated ore is then cyanided in the usual way and the gold recovered by electrolytic precipitation. Whether or not any precious metal was dissolved in the preliminary cyanide treatment

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), th

Gold extraction - Wikipedia

In 1887, John Stewart MacArthur, working in collaboration with brothers Dr Robert and Dr William Forrest for the Tennant Company in Glasgow, Scotland, developed the MacArthur-Forrest Process for the extraction of gold ores. By suspending the crushed ore in a cyanide solution, a separation of up to 96 percent pure gold was achieved.

The Mining Process - Newmont Corporation

We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution. We then “strip” the gold from the carbon by washing it with a caustic cyanide solution. The carbon is later recycled. Next, we pump the gold ...
