Flotation Research of a Fluorite Ore
Abstract:
Separating fluorite from quartz and calcite by forth flotation can be both in weak-acidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO4 can decrease the depression that water glass works on the fluorite, and acidized water glass has a selective inhibition on the silicate minerals. The close flowsheet protocolled in the experiment can obtain the content of CaF2, SiO2 in the final concentrate are 97.89%, 0.91% respectively, and the recovery rate of CaF2 is 84.18%, which is reach the requirement of the plant.
