However, it is also known as a green metal for the green patina that it acquires due to weathering.
This type of hydrometallurgical process is not entirely new. Many operations, some of them in Canada, have used hydrometallurgical processes for years for extraction of zinc and copper from sulphide concentrates. However, it was not until the 1990s that an acid-oxidative hydromet technology was developed to process nickel sulphide concentrates.
Sep 25, 2016 At the New Cornelia mine, however, the oxide and sulfide ores are sharply separated, perhaps by an ancient water level, so that the oxide ore may be mined and treated in a plant built for that purpose, and the underlying sulfide ore may be left for treatment in another plant. If copper is to be made from an ore having a total content of 1.5 per ...
Congo, the extraction of copper-cobalt ores was carried out in oxidized deposits close to the surface. The ore products were mainly supplied to concentrators or hydrometallurgical plants 1,2. The concentrators produced commercial-grade-oxide and sulde concentrates that were either processed at local copper hydrometallurgical
The processing of copper oxide ore is performed by a hydrometallurgical process called solvent extraction electrowinning SXEW. The first step, leaching, starts with sprinkling a low concentration of sulphuric acid and water solution on a stockpile of low-grade ore.

Nov 14, 2016 A large amount of hot filter cake HFC is annually generated in Iranian zinc plants. It contains 1 zinc, 1630 manganese, 525 calcium and 14.5 cobalt. Usually, zinc is selectively leached by an alkaline medium and its residue is known as alkaline leached HFC ALHFC. In the present study, the possibility of cobalt extraction from ALHFC was investigated using a creative ...
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 1114, but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
