It is extracted from its ores trough a conventional roasting method which removes the moisture from the ore. Next the nickel oxide is removed by reduction furnace which also greatly reduces the chemical bound water. Resulting in a 75% pure form of nickel. The extraction of nickel from the sulfidic ore requires a different method.

One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

Raney nickel / ˈ r eɪ n iː ˈ n ɪ k əl /, also called spongy nickel, is a fine-grained solid composed mostly of nickel derived from a nickel-aluminium alloy. Several grades are known, of which most are gray solids. Some are pyrophoric, but most are used as air-stable slurries. Raney nickel is used as a reagent and as a catalyst in organic chemistry. It was developed in 1926 by American ...
