Notes:
In this paper results regarding development of reduction process for copper production are presented. This process is applicable for small smelting plants of capacity up to 30.000 t/year, with capability for treating poly-metallic Cu-Zn-Pb concentrates with dangerous level of toxic components presence (As, Cd, Hg, …). This procedure is interesting because it can be applied for smelters that are supplied from mines at the end of exploitation so in the edge sectors poly-metallic minerals appear. Procedure consists of oxidation roasting of copper concentrate with desulphurisation degree over 98% and reduction smelting of sintered roasting products in shaft furnace of special construction. Using process of slag fuming, the degree of Cu and (Au+Ag) utilization can rise over 98% which results in good economic parameters, environment protection and low investment comparing to technologies currently used, taking in mind that phase of concentration is excluded from this technology
