Abstract

1285746 Phosphorus; silicon TEXACO DEVELOPMENT CORP 11 Dec 1969 [20 Dec 1968] 60460/69 Heading C1A [Also in Divisions C5 and C7] A process for producing elemental phosphorus and silicon comprises (a) mixing an ore thereof with a fuel composition (see Division C5) comprising cement and a carbonaceous substrate, the latter being present in at least sufficient quantity to reduce the ore, and (b) heating the mixture with oxygen to smelt the ore. Preferably the fuel composition comprises 1-3 part by weight cement, e.g. Portland cement, 6-13 parts by weight carbonaceous material, e.g. petroleum coke, lignite, gilsonite, subbituminous coal and carbonaceous materials resulting from the hydrothermal coking of organic wastes, and optionally 1-3 parts by weight of a limestone bearing material containing preferably at least 80% calcium carbonate. A flux, e.g. silica, may additionally be added. The fuel mixture should preferably be dried by steaming for one to several days before use.
