Beneficiation of a South African Wollastonite by Magnetic ...

It was found that magnetic separation successfully reduced the iron content of the ore from 1,5 percent to less than 0,3 percent after the samples had been ground to smaller than 200 micrometers. However, flotation of the wollastonite was less successful, because the surface chemistry of the three minerals involved is very similar.页数: 29
