Gold Smelting & Refining Process
The flux is a mixture of several reagent stone such as borax, silica, sodium nitrate, sodium carbonate and fluorspar. Borax is a white crystalline mineral used in glass and ceramic enamel mixes. 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 …
