Gold extraction

From the framework provided by La Brooy et al. (1994), there are three main classification categories for gold ores: free-milling, refractory, and complex. Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is 80 % 75 m (Joe Zhou, 2004).

Processing, smelting and refining gold

When gold dissolution is complete, the gold-bearing 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.
