When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Gold capture, as well as the amount of mercury released into the environment, was analyzed for two amalgamation methods and the borax method. The Amalgamation Methods . Mercury is used in gold mining because of its ability to bind to gold to form an alloy which helps separate the precious metal from rock, sand and other material. The alloy — or
