· In this work, we have applied the results of these tests to the flotation of a nickel ore that contains pentlandite, pyrrhotite, pyrite and talc. The outcome has been the development of a flowsheet (Senior et al., 1991 ) which offers the prospect of a selective separation of the pentlandite from the pyrrhotite and the talc. 2.
