Factors affecting nickel recovery from slags produced
2009-8-26 Free matte usually occurs as pentlandite-copper sulphide matte, which is often surrounded by an oxidized rim (Figure 3). The loss of matte to flotation tailings late in 1999 was mainly due to its being locked in silicate or surrounded by an oxidized rim. Recent examination also shows the presence of oversized free matte particles in the tailings—
