Beneficiation of a South African Wollastonite by Magnetic ...

Beneficiation of a South African Wollastonite by Magnetic Separation and Flotation. Samples from an orebody containing wollastonite (approximately 69 percent) with quartz calcite and iron-bearing minerals as the main impurities were investigated for possible beneficiation. This involved attempts to reduce the iron content by magnetic separation and to remove the quartz and calcite by flotation.

Wollastonite - Wikipedia

Wollastonite is a calcium inosilicate mineral that may contain small amounts of iron magnesium and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks. Associated minerals include garnets vesuvianite diopside tremolite epidote plagioclase feldspar pyroxene and calcite. It is named a
