After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%.

The limited availability of mining locations also creates a highly dependent market with the few mining countries. Substitutes can have a significant impact on the prices of nickel. During the 2007 crisis low grade nickel was used to produce so-called pig iron steel, which is of lower quality but much cheaper.

Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.

Traditional nickel laterite processing techniques use large quantities of sulphuric acid at high temperatures and pressures, resulting in expensive waste treatment and disposal of the chemicals used in the extraction process. Nickel laterites are becoming a priority for mining companies as traditional nickel sulphide reserves are depleted.

Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
