Lateritic ores contain chemically-bound water that must first be removed through a drying process in high-temperature kilns. Nickel and Copper sulphide ores need further crushing and grinding to liberate the valuable minerals from rock. The mixture or slurry is fed into a rotating mill where heavy steel rods or balls grind the rock. The ore is

In this process the sulfide is treated with hydrogen and fed into a volatilization kiln. Here it meets carbon monoxide at about 140F° (60C°) to form nickel carbonyl gas. The nickel carbonyl gas decomposes on the surface of pre-heated nickel pellets that flow through a heat chamber until they reach the desired size.
