Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.
The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications. This
Solvent extraction in hydrometallurgical processing of Polish copper concentrates 209 The Polish copper ores exhibit very favourable mineralogical composition in terms of leachability. Chalcocite (Cu2S) and bornite (Cu5FeS4), easily leachable minerals predominate in the Polish ores, while content of chalcopyrite (CuFeS2) and covellite

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of

developments in base-metal hydrometallurgy that rely on solvent extraction technology to achieve high-purity products. As examples of modern flowsheets for the processing of copper, nickel, and zinc ores and concen-trates, the Konkola, Bulong, Goro, and Skorpion flowsheets are discussed. Solvent extraction (SX) is a process by

Dezhi Qi, in Hydrometallurgy of Rare Earths, 2018. 8.4.2 Solvent Extraction Conversion of Rare Earth Sulfates to Rare Earth Chlorides [3,44–46]. In the hydrometallurgical process of treating the mixed concentrate of bastnaesite and monazite, the concentrated sulfuric acid is used to decompose the concentrate; the following step after decomposition is to leach rare earths with water.
A keynote paper for solvent extraction (SX) applications in hydrometallurgy should ‘set the stage’ for the papers that follow by discussing a commercially successful application of SX in hydrometallurgy. In addition the paper needs to discuss a complete metal recovery process for the simple reason that an SX process

1960s when solvent extraction was applied for the first time to extract a rela- tively cheap metal — copper. At present, solvent extraction technology is wide- spread, well accepted, and highly efficient. Solvent extraction had its origin in the discovery, by Christian
The development of ion exchange, solvent extraction, and other processes has led to an extremely broad range of applications of hydrometallurgy, now used to produce more than 70 metallic elements. Besides most gold and much silver, large tonnages of copper and zinc are produced by hydrometallurgy.
