Experimental Study on the Selectability of Calcite Type Wollastonite
Calcite type wollastonite contains impurities such as calcite,quartz,and dolomite,and its added value is not high.In order to effi-ciently utilize calcite type wollastonite ore,flotation methods were used for impurity reduction treatment.The results showed that grinding fineness-0.074 mm accounting for 60%,using 300 g/t oxidized paraffin soap as collector,removing impurities such as calcite by flotation,and then using 60 g/t dodecylamine as collector to remove quartz impurities,a wollastonite concentrate with a concentrate grade of 96.70%and a recovery rate of 88.58%was obtained.
