Electrowinning Smelting For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand.
The Gold Smelting Process - Melting, Smelting Refining.
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.

In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the slag will be extremely hard and non-homogeneous. Other negative effect is to avoid the separation of phases into the molten charge. Silica is an acid flux and reacts with metallic oxides forming stable silicates.

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it.
