Direct extraction of nickel and iron from laterite ores

The carbonyl method of refining nickel and iron was invented more than 100 years ago and has been used for refining of nickel commercially. CVMR® developed the process of direct extraction of nickel and iron from laterite ores as metal carbonyls which in turn produced pure nickel and iron metals.

This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to lowgrade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to

employed to recover the ore after the removal of the overburden (Whittington & Muir, 2000, pp.527600). The laterite ore consists of fresh saprolite, limonite and nontronite. These ores represent various layers in the laterite bedrock. Limonite consists mainly of goethite, a hydrated iron oxide such as FeO(OH), HFeO2, or Fe2O3·H2O.
