The second principle of ferronickel smelting is that laterite ores cannot be smelted to nickel metal alone, i.e., separately from iron. This is because (1) garnierite concentrates always contain 5–10 times more Fe than Ni and (2) oxygen is only slightly more strongly bonded to Fe than to Ni—i.e., FeO in calcined concentrate is almost as easy to reduce as NiO.
