The impure nickel reacts with carbon monoxide at 5060 C to form the gas nickel carbonyl, leaving the impurities as solids.

nickel laterite ore processing research papers

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.
