Your Process Challenge for Copper Heraeus
The liquid ‘matte’ is refined in a converter process where ‘blister’ copper is produced with > 98% copper content. Blister copper is then casted into intermediary anodes which are further refined into copper cathodes (99.99% pure copper) through an electro-refining process. Cathodes are re-melted and processed into final end user products.In the copper refining process (Fig. 1 (a)), the mined rock is first ground in a crushing unit [5] and then separated, typically via a floatation unit, into sulphide-containing (chalcocite (Cu 2 S), covellite (CuS) and chalcopyrite (CuFeS 2)), and oxide-containing (tenorite (CuO) and cuprite (Cu 2 O)) products.The sulphide ore is processed via a Integration assessment of the hybrid sulphur cycle with a copper

A Review of the Cyanidation Treatment of Copper-Gold Ores
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has The process simulations covered the process from sulfidic copper ore to blister copper but excluded the impact of downstream processes such as fire refining, electrolytic refining, wet gas cleaning and sulfuric acid production since these are performed relatively similarly in all the technologies compared with minor influence on the outcomeComparison of environmental performance of modern copper

with copper solvent extraction and electrowinning (EW). Now approaching a 20% share of primary copper produc-tion, heap leaching offers reduced costs compared with the costs of smelting and refining. Those savings result from the omission of energy-intensive ore grinding and flotation. Limited resources of oxidized copper ores, theThe benefits gained by drying copper concentrates prior to the smelter include: ¹. Smaller gas handling system (and subsequently reduced capital cost) By drying copper concentrates, producers can ultimately reduce costs associated with fuel and exhaust gas handling, as well as have a more concentrated stream of SO 2,which is Drying Copper Concentrates FEECO International Inc.

Comprehensive Review on Metallurgical Upgradation
Mu et al. reported a process for synchronous extraction of nickel and copper from a mixed oxide-sulfide nickel ore in a low-temperature roasting system. In this process, sodium sulfate was used as an additive for improving the extraction of nickel by converting into Na-pyrosulfate, and more than 97% of nickel could be extracted after This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining. At this point, the copper is cast into anodes, the shape and weight of which are dictated by the particular electrolytic refinery. LeachingCopper processing Roasting, Smelting, Converting
