How to Process Nickel Laterite, the New Focus of Nickel Mining

 · To prepare the lateritic nickel ore required for pyrometallurgy, we need to crush and sieve the raw ores. Coarse ores (the particle size is within 25mm-150mm) will be calcinated, while fine ores will be discarded or calcinated after pelleting. Note that the lower the water content of the lateritic nickel ore, the better.
