In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder. Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel. Smelting processes the concentrate further, creating nickelrich matte, while impurities are removed as slag.

The non magnetic ore is sent to a series of rougher, cleaner flotation cells, and produces a 31% copper concentrate. The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate.

because of the low nickel content and thus large amounts of ore to be treated. This is due to the fact that the nickel content of laterites cannot be upgraded to any significant degree as is the case with sulphides.
