Research on Gold Leaching from a Refractory Gold Concentrate in Copper

Thiosulfate is a green gold leaching agent that shows great potential to replace the highly toxic cyanide. Ammonia is traditionally used as the copper ligand in thiosulfate solutions to reduce the reactivity of copper ions towards thiosulfate, but it is a toxic reagent. As a result, efforts to replace ammonia with another complexing agent have received increasing attention. …

SX Solvent Extraction Process Principles Theory

A high copper/nickel ratio on the copper loaded organic is obtained by using an extra extraction stage in which copper crowds nickel from the loaded organic, i.e., the copper in an ammoniacal copper and nickel containing solution, when contacted with an organic loaded with nickel, will replace some of the loaded nickel.

Producing Copper Nature's Way: Bioleaching

The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vil solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.
