The Gold Smelting Process Melting, Smelting & Refining

18/01/2017 Gold smelting is an important process in the production of gold. It enables gold miners to separate impurity materials from pure gold that is desirable in the market. Smelting often produces gold to the purity over 90%. To improve the quality of the gold mined, gold miners have to refine the gold. This process takes the smelted gold and using a number of methods removes the often difficult to
