The copper extraction and metal formation is a "one-pot" process using a molten eutectic mixture of NaCl, KCl and ZnCl 2 as both the lixiviant (to dissolve copper and copper oxide from copper concentrate ore or slag) and as an ionically conductive electrolyte medium for electrodeposition of copper ions as copper metal. Several eutectic molten halide salt mixtures …

OXIDE COPPER CONCENTRATES— The high grade concentrates are, after automatic sampling, fed to Dorr Type thickeners (40′ and 50′ dia.).
