Abstract

512,502. Alloys ; extracting metals. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). March 18, 1938, Nos. 8464 and 18562. [Class 82 (i)] [Also in Group III] Difficultly reducible oxides of elements of the 2nd-7th periodic groups, particularly chromium, beryllium, magnesium, aluminium, silicon, titanium, thorium, vanadium, niobium, tantalum, molybdenum, tungsten, uranium, and manganese, or compounds of such elements which are converted into oxides under the working conditions, are reduced by heating, for example at 900-1,300‹C., under reduced pressure in presence of both carbon and hydrogen. Metals, preferably in finely-divided form, such as copper, iron group metals, or noble metals such as silver, or oxides of readily reducible metals, may also be present. The carbon may be in the form of wood charcoal, graphite, carbon black, low temperature lignite coke, metals or alloys rich in carbon, sugar, or wood meal. The production of the following metals : chromium, manganese, vanadium, tantalum, and of the following alloys : chromium-nickel, nickel-uranium, molybdenumuranium. copper-beryllium, iron-niobium, nickel-silicon, nickel-titanium, nickel-aluminium, iron-chromium, is specifically described.
