Pyrite Reverse Flotation

Its reverse flotation of magnetite where pyrite is floated. Though the pyrite concentration looks to be lower (with S<0.5% in feed) it may be worth looking at the pyrite floats around the Kalgoorlie area in Western Australia as these systems are generally highly saline (off the top of my head KCGM Fimiston and Kanowna Belle) and do employ xanthates.
