Abstract Separating fluorite from quartz and calcite by forth flotation can be both in weakacidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO 4 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 CaF 2, SiO 2 in the final concentrate
