Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold

How to Choose Gold Smelting Flux Superb

Silica is quite similar to Borax in its gold smelting flux properties. It is selectively soluble with Gold and silver and similarly allows for the easy separation of pure metal from slag. By forming silicates with metal oxides, Silica ensures the stability, homogeneity, and low viscosity of the slag.
