In this research a procedure has been devised which rejects much of the pyrrhotite while maintaining the necessary level of talc rejection. In batch tests on an ore containing pentlandite, pyrrhotite, pyrite and talc the procedure rejected 57% of the iron sulphides and 98% of the talc and recovered 81% of the nickel in a concentrate assaying 16.5% Ni.

-DTP in the froth flotation of pentlandite containing ore. INTRODUCTION Nickel sulphide mineral ores amounts to more than fifty percent of all commercial nickel (Senior et al., 1995). There is a growing demand for nickel and it is projected that the current nickel sulphide reserves may be depleted by 2030 (Tundermann et al., 1996).

Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained.

Froth flotation is one of the most versatile and widely employed mineral processing techniques given it can selectively separate valuable minerals from gangue (i.e., waste minerals) in low-grade, complex (polymetallic) ores having a particle size too small to be effectively processed using other techniques (Rahman et al., 2012; Wills et al., 2006).

Potassium amyl xanthate (PAX) and sodium isobutyl xanthate (SIBX) are traditional thiol collectors used in the bulk and selective froth flotation of nickel and copper sulfide mineral ores. Individually, they are not selective enough for economical low-grade nickel froth flotation. Therefore, more selective collectors or co-collectors are required.
