Abstract: A method for operation of a flash smelting furnace comprising a reaction shaft, a settler connected at one end thereof to the lower portion of the reaction shaft and having a slag discharge port and a matte discharge port disposed on the side thereof, an uptake connected to the other end of the settler and at least one concentrate burner disposed to at least one of the top of the reaction shaft and the ceiling of the settler, in which the concentrate burner comprises at least a concentrate shoot, an oxygen blowing tube inserted in the concentrate shoot and an auxiliary fuel burner inserted into the oxygen blowing tube. In this method, the lower end of the oxygen blowing tube is protruded downward to lower than the lower end of the concentrate shoot and an amount of oxygen at least greater than that required for the auxiliary fuel is blown as an industrial oxygen by way of the oxygen blowing tube into the furnace. Oxygen efficiency can be improved remarkably while the rate of dust occurrence can be reduced.

Abstract: A pyrometallurgical refining process for obtaining one or both of zinc and lead from a sulfide concentrate, in which an iron-silicate slag or iron-silicate slag containing lime is formed and the sulfide concentrate, incombustible materials, and flux, together with at least one of industrial oxygen, oxygen-enriched air, or air, are blown into the slag to cause a reaction; as a result of the reaction, the major part of the zinc and part of the lead in the sulfide concentrate and the incombustible materials are dissolved in the slag, to arrange the slag and a matte and/or metal from one part of the lead in the raw material. A reducing agent such as heavy oil, pulverized coal, powdered coke, or the like is blown through the resulting slag, and the zinc and the lead in the slag are volatilized then condensed to obtain molten zinc and molten lead.

Abstract: A flash smelting furnace includes a reaction shaft defining a reaction chamber therein, a plurality of reaction air blowing pipes passing through the side wall of the reaction shaft for blowing reaction air into the reaction chamber, and at least one concentrate burner attached to the top end of the reaction shaft and comprising a concentrate chute, a tubular auxiliary fuel burner extending vertically through the chute, a tubular oxygen blowing pipe concentrically surrounding the auxiliary fuel burner and a dispersion cone attached to the lower end of the oxygen blowing pipe. The air from the blowing pipes disturbs the jet stream of mixed smelting material and reaction gas in the reaction chamber, thereby achieving a uniform mixture of the material and the reaction air and extending the retention time of the material in the reaction shaft.
