A previous study also found that SS could be adsorbed more strongly on the calcite surface than on scheelite (Gao et al., 2016). Thus, a new attempt to inhibit the gangue mineral calcite by applying sodium silicate will be performed in the presence

The Role of Gangue Mineralogy on Flowsheet Development in Fluorite

06.03.2020Froth flotation is reported to be the most efficient and economically viable process for the production of an acid-grade product with a CaF 2 content of at least 97%. Selective flotation of fluorite from gangue minerals, e.g., calcite and barite, is challenging because these minerals have similar physicochemical properties.

Flotation Separation of Scheelite from Fluorite and Calcite

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 scheelite rough concentrate indexes. It is
