TH53176B - Method for smelting copper concentrate - Google Patents

Abstract

DC60 (18/03/56) This invention involved a smelting method of a copper sulfide concentrate, in which the copper sulphide material was smelting in a smelting furnace (1 ) To create copper blister and slag according to this method. At least part (3) of the smelting furnace feeder (1) is copper sulphide-containing material (3), obtained through the sulfide-containing material (2), which has been fed. to Additional hydrologic operations (hydrometallurgic) (12,19) of the sludge (11) occurred in Smelting process The invention involved a method for smelting copper sulfide concentrates. Which in this method Materials containing copper sulphide were smelted in a smelting furnace (1) for the formation of copper blister and residue according to this method. At least the (3) of the smelting furnace's feed (1) is copper sulphide material (3), obtained by means of sulfide-containing material (2), which is fed into Additional hydrothermal (12,19) operations of sludge (11) occurred in the smelting process.

Claims (2)
