Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
Laterite ores have three nickel-bearing layers, limonite, smectite and saprolite. Cobalt is also produced from Central African copper—cobalt ores. Platinum group metals are extracted from sulfide ores. Certain amount of nickel, cobalt and platinum group metals .

History. Ores containing cobalt have been used since antiquity as pigments to impart a blue colour to porcelain and glass. It was not until 1742, however, that a Swedish chemist, Georg Brandt, showed that the blue colour was due to a previously unidentified metal, cobalt. In 1874 the output of cobalt from European deposits was surpassed by production in New Caledonia, and Canadian ores assumed ...
Oct 22, 2012· Most oxide copper ores are not amenable to present-day flotation techniques and are not rich . being developed for the treatment of copper, nickel and cobalt sulfide ores . Cobalt extraction techniques – Wikipedia, the free encyclopedia . Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a ...
Cobalt and platinum-group elements are also present, either dissolved in the pentlandite or present as distinct minerals. Sulphide ores that are mined for nickel and cobalt typically contain 1.5%–3% Ni and 0.05%–0.1% Co. Concentration, Smelting and Converting to Matte
In Madagascar, Sherritt's Ambatovy nickel cobalt JV (operator Sherritt 12%, other partners include Sumitomo and Korea Resources Corporation) mines, processes, refines and markets Class I finished nickel. In 2019, production at Ambatovy was 33,733 tonnes of finished nickel and 2,900 tonnes of cobalt.
Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ...
cobalt compared to major metals such as copper, nickel, iron and zinc; which is fortuitous since in nature cobalt occurs in relatively minor quantities in association with ores of other metals – predominantly copper, nickel and silver/arsenic. Hence cobalt is seldom mined solely in its own right and its recovery is usually viewed as a by-product.
