Effect of different additives on grade and recovery of nickel and iron in ferronickel concentrate: (a) nickel recovery, (b) iron recovery, (c) nickel grade. With the increase of Na 2 S dosages to 10% as shown in Fig. 1, the nickel grade exhibited a significant improvement, from 3.69% to 10.86%; nickel recovery also increased to 92.09%.

The invention relates to a method for processing lateritic (oxidised nickel) ore, containing nickel, cobalt and iron. The method for processing comprises preparing a ferronickel raw material (ferronickel bloom or a cast iron admixture with nickel) by appropriate techniques, and refining the ferronickel raw material in a lateral blast furnace.
