Nickel (Ni) ore processing | Rigaku Global Website

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 nickel-rich matte, while impurities are removed as slag.
