2015-10-1 Flotation Copper-Zinc Ores. The separation of copper-bearing from zinc sulphides is effected by two-stage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a lead-zinc plant; the zinc sulphides are floated in theget price
2022-8-10 However, copper is stored in nature mainly in the form of sulfidic ores, such as chalcopyrite, bornite, covellite, digenite, and chalcocite [6, 7]. Copper ores commonly consist of a low concentration (0.5–2 wt% Cu) of copper iron-sulphide or copper-sulphide minerals (e.g. chalcopyrite CuFeS 2 or chalcocite Cu 2 S) in combination with a largeget price
2015-7-26 Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper (II) sulphate solution. Concentration of the copper (II) sulphate solution by solvent extraction.get price
2022-8-8 Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, get price

2004-1-1 The separation of copper from nickel in such ores has seen a similar level of development. From the late 80s to very recently, the use of flotation columns, the use of pyrrhotite depressing reagents and the improved understanding of the complex mineralogy of chalcopyrite, pentlandite and pyrrhotite have considerably increased copper / nickelget price
2022-1-25 Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.get price
