Leaching Chemicals
Leaching is a gold extraction process in which the ore is treated with certain chemicals which help to convert the precious metals into soluble salts while impurities remain insoluble. It is a method used for extracting gold from low-grade ore by converting gold to a water-soluble complex.
List of Leaching Chemicals:
Extensively used in cyanide leaching for the extraction of gold.
Helps in the adsorption of gold-cyanide solution.
Responsible for the elution stripping of adsorbed gold on activated carbon.
Acts as an accelerator in gold cyanidation.
Detoxifies cyanide in gold extraction.
Also detoxifies cyanide in gold extraction.
