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 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.

By the analysis of oleinic acid flotation of fluorite and hematite, it is inconsistent to use thermodynamic approach to explain the flotation effect by the chemical adsorption of the reagent only. The authors propose a hypothesis that collecting ability of a flotation reagent relates with the activity of its physical adsorption at the air-liquid interface.
