As the main minerals in the fluorite ore are fluorite, calcite, and quartz which have their isoelectric point (IEP) at different pH, the addition of dispersant changes the pH of slurry and endows the minerals with different charges, which are beneficial for the separation of the minerals and getting the high concentrate grade of CaF 2 [13, 14].

01/09/2017· Flotation recoveries of celestite, fluorite and calcite in presence of the depressant CA as a function of the pH. Fig. 4 presents the effect of the pH on the floatability of celestite, fluorite and calcite in the presence of depressant CA.
4Keywords: scheelite, fluorite, calcite, regulator, flotation separation . INTRODUCTION . In scheelite flotation, gangue minerals such as Fluorite and Calcite have the same surfaceactive cation (Ca-2+ ) with scheelite minerals and strong binding capacity with the fatty acid collectors. So the flotability of scheelite is a close with that of Fluorite and Calcite and it is difficult to get good
trona), semi-s oluble sa It minera Is (ph asp hate minerals, fluorite, calcite, mica, quartz, and feldspar), and energy minerals (coal and oil sands). As a consequence, some flotation separations are accomplished from saturated brine, while other separations are achieved in solutions of rather low ionic strength. Also it is worth notiog that certain nonsulfide minerals are naturally

Fluorite usually coexists with calcite, quartz and other silicate minerals in deposits. By now, fluorite is mostly recovered from these gangue minerals by froth flotation, through which can produce fluorite concentrate with grade up to 99% (by weight). In fluorite flotation, fatty acids and their derivatives are used as collectors for fluorite [1,2]. The common opinion for the collecting
