<p>PROCESS FOR MAKING THE CHLORIDES OF LEAD, ZINC, COPPER, SILVER AND GOLD A process for forming a metal chloride of a metal or its compound comprising forming a liquid fused salt bath mixture of at least two metal chlorides with one of the chlorides being selected from the group consisting of ferric chloride, ferrous chloride, cupric chloride and cuprous chloride, and introducing the metal or compound into the liquid fused salt bath in the presence of a chlorine source to form the metal chloride and elemental sulfur, and recovering the formed chloride from the liquid fused salt bath mixture. Chlorine gas or sulfur chloride may be introduced into the bath as an additional source of chlorine for reaction with the metal and for the generation of a portion of the ferrous chloride or cuprous chloride into ferric chloride or cupric chloride.</p> |
