  • Gold Smelting Amp Refining Process 911 Metallurgist

    Feb 28, 2016 Normally, the boraxsilica ratio is 21. 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.
