Method for Smelting of Copper sulfide Concentrate, which occurs by oxidation of the Iron Concentrate, with the help of Cao and SiO2 as fluxes.And where the slag produced must meet certain requirements with regard to the weight of Cao, SiO2, and fe feox present in it.

摘要

Method for Smelting of Copper Sulphide Concentrate essentially includes the steps of: adding the Copper sulfide Concentrate, the basic material of SiO2.Cao and Basic material to melt and bring elconcentrado Sulphide Copper smelting slag by oxidation to produce Product and at least one selected from the group of white metalAnd blister Copper, so that at least part of the Faith in the Copper sulfide Concentrate is transferred to the slagWhile at least part of the SO2 is removed in the form of Copper concentrates and that at least in the form of metal or white blister copper and where the composition of the slag is controlled.So that the weight ratio of CAO / (Si02 + CaO) is in the range between 0.6 and 0.85 while the weight ratio of Fe / (feox + SiO2 + CaO) is in the range of 0.5 to 0.6.
