Gold Smelting Refining Process
Normally the borax/silica ratio is 2/1. Sodium nitrate is an oxidant for iron copper and zinc. When the charge is near 500 o C sodium nitrate produces oxygen. Sodium carbonate is an alkaline flux whose melting point is 850 o C and reacts with silica forming sodium silicate. The latter reacts with oxides and produces other oxidized compounds.
