Abstract
553,315. Treatment of ferruginous materials for recovery of iron and other mineral constituents. ABBEY, A. (Titan Co., Inc.). Nov. 12, 1941, No. 14587. [Class I (iii)] Ferruginous material containing also the valuable mineral constituents is treated by calcining the finely divided material under reducing conditions to reduce the major portion of the iron to metallic form, oxidising this to iron oxides and separating the oxides from the other metallic constituents. The other mineral constituents may be manganese, copper, chromium, aluminium, vanadium, titanium and columbium, the calcining may be at a temperature between 800‹ C. or 1,000‹ C. and may convert 50 to 95 per cent. of the iron to the metallic state. The oxidation may be effected by wetting the mass with water and treating with an oxidising gas at a temperature between 40 and 200‹ C. The separation of the iron oxide may be by washing the iron oxide off with water. Pigments and other synthetic products may be prepared using the iron oxide and other residual products thus obtained. Coal, coke, charcoal, carbon monoxide, hydrogen, &c. may be used in reducing in a rotary kiln or stationary retort. In the oxidation air and steam may be present and electrolytes such as NaCl, NH 4 Cl, MgCl 2 , CuCl 2 , HCl, and FcCl 3 may be used as accelerators. The separation of oxide may be electromagnetic, or by wet flotation, electro-flotation or air separation such as by elutriation. Specification 547,898 is referred to.
