    Jul 29, 2018 Nickel is a toxic element which, when released in effluent, often occurs in higher concentrations than normal background levels and therefore poses a severe threat to ecosystems. As Figure 4 below shows, 39% of global nickel reserves – made up entirely of laterites – are found in locations exposed to high or extreme biodiversity risks

    With appropriate comminution, magnetic separation, and froth flotation technology, the nickel ore may be isolated from that of iron and copper, with copper and iron as the important by-products of the nickel refining process. Concentrated nickel-bearing ore is roasted, smelted, and converted to a matte containing nickel and copper sulfides. Upon cooling, the matte forms nickel and copper sulfides and nickel-copper alloy
