Abstract
Process for beneficiating ores which contain metallic values in the form of refractory oxides as well as in the form of pyrometallurigically reducible metallic compositions. The portion of the ore which is pyrometallurgically reducible is so reduced to produce a metallic-refractory oxide product. The metallic portion of the product is solubilized by utilizing the product as a consumable anode in an aqueous saline electrolytic cell. A substantially metallic-free refractory oxide product is recovered from the electrolytic cell.
