Abstract

A method for creating a beneficiated low-grade ore includes determining a desired finished product based on the composition of the low-grade ore, concentrate or waste-oxides. Blending this low-grade raw material source with carbonaceous material and flux (as needed) with the consideration of complete reduction and carburization of the metal intended for removal can be conducted such that the metal intended for removal is separated from a fusible slag which has affinity to the other metals in the low-grade ore. Selectively carbothermically reducing and smelting the raw material mixture produces a metallic product and a slag, and the slag can be fused to separate it from the metallic product. These steps can be repeated to selectively reduce metals sequentially, and transform them into commercially usable products.
