Improving Fluorite Ore Flotation Effect

Improvement Effect of FeSO 4 ·7H 2 O on Flotation Separation of Scheelite from Fluorite ...

· In this study, FeSO 4 ·7H 2 O was used as an auxiliary depressant to improve the selective depression effect on fluorite. Microflotation tests using oleic acid as the collector showed that the preaddition of FeSO 4 ·7H 2 O and subsequent addition of sodium silie (SS) resulted in a stronger selective depression effect on fluorite compared with SS alone.

The effect of polyacrylic acid on the surface properties of calcite and fluorite .

fluorite ore were studied using microflotation tests, and the results were analyzed with Fourier transform infrared spectroscopy (FTIR) and Xray photoelectron spectroscopy (XPS) analyses. The flotation tests indied that the preferential adsorption of PAA onto calcite rather than sodium oleate (NaOl) could selectively depress the flotation of calcite, allowing its separation from fluorite ...
