gold processing Britannica

Gold Processing Britannica

The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts

The most common method is to roast gold-bearing minerals at temperatures of 450 to 750 C (840 to 1,380 F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves , in which the minerals in an aqueous slurry are treated at high temperature and pressure with oxygen-bearing gases.
