In mineral processing, the valuable minerals are liberated from the ROM ore and separated from the gangue minerals, hence producing a higher quality product (concentrate) that is further refined to extract the metals of interest. The run-of-mine (ROM) ore extracted during mining operations usually undergoes primary mineral processing in the vicinity of the mine, as is the case for many copper processing plants established in the Central African Copperbelt region. Keywords : copper, copperbelt, solvent extraction, mineral processing, crystallization. The advantages and disadvantages of the two processing routes are compared. The copper sulphate purity is such that it can also be added intermittently to the EW strong/advance electrolyte circuit, although care must be taken to maintain the sulphate balance in the EW circuit. When added to SX, the sulphate associated with the copper sulphate is recovered as sulphuric acid in the raffinate, supplementing the fresh acid requirements for leaching. The end product is attractive for copper cathode producers that have un-utilized solvent extraction (SX) and electrowinning (EW) capacity. An advantage of satellite copper sulphate production is that copper units supplied to the refinery for cathode production require less secondary processing than a DMS concentrate. The demand for LME-grade copper metal is orders of magnitude higher than that for feed-grade copper sulphate. Although the production of feed-grade copper sulphate offers producers a premium on the final product, the market demand is limited. Similar technology has been successfully implemented in South America however, these plants have targeted copper sulphate as a final product, primarily for the animal feed additive market. The alternative process comprises crushing and screening of the ore, heap leaching, solvent extraction, and copper sulphate crystallization. In this paper a processing route that produces a copper sulphate product at the remote ore location is presented as a possible alternative to the production of a concentrate by dense media separation (DMS). These new deposits are often situated some distance from the refineries, thus necessitating upstream mineral processing in order to produce a concentrate that is then transported to the refinery, usually by road. As the high-grade deposits at primary refinery sites become depleted, new ore deposits are exploited. Many hydrometallurgical copper refineries have been established in northern Zambia and in the Haut-Katanga and Lualaba provinces in the Democratic Republic of Congo to treat such orebodies. The Central African Copperbelt is well known for its high-grade copper-cobalt deposits.
