    Pentlandite is an important ore of nickel. However, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.

    A typical example of a nickel sulfide plant operating with highly floatable talcose gangue is at Trojan mine in Zimbabwe. The Zimbabwean sulfide deposits contain very low grades of nickel (0.6%) and copper (0.04–0.4%). The easily floatable non-sulfide minerals dilute the grade of the concentrate and also result in nickel losses into the tailings.
