In the refining of molten gold, the silver and the copper impurities are chlorinated and form a molten chloride mixture on the surface of the gold. This silver chloride-copper chloride salt is known as Miller chlorides. In the present work, the reduction of this chloride with sodium silicate and carbon was studied. A silver-copper alloy, a silica-based slag and a sodium chloride salt were produced. The overall reactions were as follows: 2AgCl + Na2O.SiO2 + C = 2Ag + 2NaCl + SiO2 + CO and 2CuCl + Na2O.SiO2 + C = 2Cu + 2NaCl + SiO2 + CO The effects of charcoal, sodium silicate, borax additions and crucible type on the metal recovery and composition were determined. Experiments were performed in resistance, gas-fired and induction furnaces. The results show that even at relatively high temperatures, such as 1400 degrees C, sodium silicate additions considerably in excess of the stoichiometric are required to achieve silver recoveries approaching 100 percent. For a given sodium silicate addition, borax additions improved the silver recovery. Mechanical mixing of the solid reagents followed by smelting in a clay graphite crucible in an induction furnace resulted in the highest metal recoveries and rapid material throughput.
