METHOD FOR BENEFICIATING TITANIUM BEARING MATERIAL CONTAINING IRON; REDUCTION PROCESS USES PARTICULATE CARBONACEOUS MATERIAL AND THEN SOLID HYDRATED FERROUS CHLORIDE UNDER REDUCING CONDITIONS

摘要

Process for beneficiating particulate titanium bearing material containing iron oxides comprising: (a) subjecting said particulate material to reducing conditions in the presence of a particulate carbonaceous material, (b) feeding the products resulting from step (a) to a mechanical reduction kiln and contacting the products with solid hydrated ferrous chloride under reducing conditions which cause additional iron oxide to be converted to metallic iron and the solid hydrated ferrous chloride to vaporize, (c) removing the products resulting from step (b) from the kiln, (d) contacting the gaseous product from step (c) with water under conditions which form solid hydrated ferrous chloride, and recycling the solid hydrated ferrous chloride to the kiln, and (e) separating the metallic iron and titanium bearing material from the solid product from step (c). c
