The planned greenﬁeld SX/EW Reﬁnery more than doubles Katanga’s capacity, with increased recoveries and higher grade metal production. Its design has two modules, each producing 80,000 tpy copper and 10,000 tpy cobalt.
The Noranda process, as originally designed, allowed the continuous production of blister copper in a single vessel by effectively combining roasting, smelting, and converting into 1 operation. Metallurgical problems, however, led to the operation of these reactors for the production of copper matte.
Process The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
steadily. Cobalt is produced mostly as a by-product of other major metal extraction processes – mainly copper and nickel – and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo (DRC) copper-cobalt production is coming to the fore once again after a 20-year period of decline.
