How To Choose Gold Smelting Flux Superb

Catalysis Since Gold smelting flux is made up of chemical substances, they can serve as catalysts to speed up the selective oxidation process. This makes the separation of slag from precious metal quicker. Without the use of Gold smelting flux, the flow of molten precious metal to the bottom is sluggish.

Extracting Gold HowStuffWorks

Extracting Gold Howstuffworks

The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.
