Pentlandite is an iron-nickel sulphide mineral, a critical source of the metal, and is often finely disseminated within another low nickel bearing matrix, pyrrhotite. Flotation is generally effective in extracting the sulphide mineral, despite its relatively poor flotation kinetics (Allison and O'Connor, 2011).

For example, thiosulfate reduced the activating effect of calcium in nickel flotation but increased it in copper flotation, in region where galvanic interaction with mill iron was effective. In addition, calcium seems to have prevented the "activating" effect of thiosulfate on pyrrhotite in the end of the test.

It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C.

Nickel recovery and grade were increased by 2.7% and 2.1% respectively, after adding the second dose of the depressant after 1 minute into the flotation test. The results indicated that the fast floating MgO can depress the valuable mineral if the depressing effect of the depressant is short-lived, which in turn leads to reduced nickel recoveries.
