Nickel ore processing. The analysis of nickel concentrate, filter cake, furnace matte and furnace slag is demonstrated. Background. 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 ...

As mentioned above, major reserves of nickel are contained in laterite ores, which have traditionally been treated by pyrometallurgical methods. Hydrometallurgical treatment, by direct acid leaching of the ore at temperatures above 240°C, is however an alternative treatment option for several new projects.

The nickel present in nickel laterites is in very complex form as well as the content of the metal is very less, hence the laterite ores have been neglected for nickel extraction. Because of such reasons the conventional mineral processing (pyrometallurgical and hydrometallurgical) techniques are not economically suitable for nickel extraction.
