Gold Smelting & Refining Process

Basically the ore is mixed with a mixture of fluxes and during the smelting process precious metals are liberated and most of heavy metals are trapped by the fluxes. However, lead is the key element due to collect precious metals. The latter product is reprocessed by a cupellation stage so that we can have a gold-silver alloy that will be leached selectively to calculate the gold content.

Mining and Refining – Process - World Aluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to ...
