IN MINING MINERAL PROCESSING
2018-11-16 Principally, gold occurs as a native metal, usually alloyed with silver as an electrum, or with mercury as an amalgam. Gold may occur as sizeable nuggets, fine grains or flakes in alluvial deposits or microscopic particles embedded in rock minerals. Although comparatively rare, gold occurs in chemical compositions with other elements such as calaverite, sylvanite and petzite, to name a few. Historically, the extraction of the metal relied on gravity concentration, where simple tools such as pans and wash tables were used. Gravity concentration could be directly smelted too for gold bars if the gold was present in the ore as coarse particles. In today’s era, which is continually demanding maximum yield and concentration from the mining process, there are a series of chemical procedures employed to extract the gold
