Abstract
1349041 Antimony oxides and acid OCCIDENTAL PETROLEUM CORP 25 Jan 1972 [30 Dec 1971] 3432/72 Heading C1A Antimony oxides and or antimonic acid are produced from stibnite bearing ores or concentrates by; (a) leaching with an aqueous ammonium sulphide and sulphur containing solution to form a mother liquor containing antimony sulphide; (b) eliminating ammonia from the mother liquor and then precipitating antimony sulphide and sulphur; (c) oxidizing the precipitate with an aqueous nitric acic solution to form a slurry of antimony oxides and antimonic acid together with sulphur; and (d) separating the antimony compounds from the solution and from the sulphur. The leaching solution preferably comprises 5 to 30% by weight of (NH 4 ) 2 S and 0.1 to 10% by weight of sulphur. It may also contain up to 18% by weight of NH 4 OH. The ammonia may be eliminated by neutralization or distillation. The aqueous nitric acid solution preferably contains 1 to 70% by weight of HNO 3 and oxygen may be present at a pressure of 0 to 300 psig. The sulphur may be separated from the product with a solvent, preferably one of carbon disulphide, trichloroethylene and tetrachloroethylene. The leaching may be carried out at temperatures from ambient to 90‹ C. and the oxidation at between ambient and 150‹ C.
