For example, nickel-plated faucets may contaminate water and soil; mining and smelting may dump nickel into waste-water; nickel–steel alloy cookware and nickel-pigmented dishes may release nickel into food. The atmosphere may be polluted by nickel ore refining and fossil fuel combustion.
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel.They depend on the concentration of cobalt and the exact composition of the used ore
The processing plant will process 4.2 millions tonnes of nickel ore to produce 3.6 millions tonnes of autoclave feed. The nickel/cobalt hydroxide is forecasted to be 103 thousands tonnes, containing 40 thousands tonnes of nickel metal and 4.1 thousands tonnes of cobalt metal produced annually.
Lateritic Nickel Ore Processing. While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below.

Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:
Nickel Ore Mining Process Brief Introduction Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods: The most important is the flotation.
removes most of the deleterious impurities, and thus produces a nickel-cobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way; however, not all sulphide ores .
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel.
