It is common that gold ore be processed by two methods gravity is used to remove the coarser gold from an ore and afterward the ore is processed by cyanide to recover the fine particles of gold and silver. Gravity concentration methods are the ones most commonly used by the individual prospector.
Processing, smelting and refining gold. 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. SMALL SCALE REFINERS;
Hard Rock Mining Gold and Silver Ore and processing it
Such ores are referred to as refractory, and they frequently contain the sulfide minerals pyrite, pyrrhotite, or arsenopyrite. Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast goldbearing minerals at temperatures of 450#176; to 750#176; C (840#176; to 1,380#176; F) to destroy the interfering sulfides.
