Nickel and Cobalt Production   ScienceDirect

Nickel and Cobalt Production ScienceDirect

Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron < 15 % Fe ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte
