Froth flotation of fluorite: A review - ScienceDirect

01-04-2021· The next stage, i.e., the flotation of the mixed concentrates, has two options: a) regular flotation, where the fluorite is floated using fatty acid as the collector, while barite is depressed by dextrin, tannin or malysite; b) reverse flotation, where hydroxy sulfate ester is used as the collector to float the barite, while the target mineral, fluorite, remains in the tailing [172,173].Enrichment of Molybdenum and Fluorite by Flotation of,,In the first step of flotation, the fluorite left in the tailing contained 29.6 % of CaF2. After flotation of this tailing, concentrate grade of CaF2 raised to 96 %. 0.5 % of sulfur was found in this concentrate. It was concluded that this concentrate contained fluorite with suitable particleThe complex behavior of fatty acids in fluorite flotation,coagulate onto the surface of fluorite and make it readily flotable. The objective of this research was to delineate the solution chemistry of a model fatty acid, the interfacial behavior of its precipitates, and their effect on the flotation behavior of fluorite.

Commonly used depressants include, quebracho for calcite and lignin sulfonate and sodium fluoride.for barite andFlotation separation of fluorite from calcite using,,01-07-2020· The most commonly used method to improve the content of fluorite is froth flotation , , . However, fluorite usually coexists with some other gangue minerals, like dolomite, barite and calcite, etc. , . The gangue minerals need to be removed during the flotation of fluorite.(PDF) Mechanism of collector adsorption in fluorite flotation,The best results are obtained using a combination of quebracho and white dextrin as depressants, reaching 74% of fluorite grade for modified column flotation and 70.5% for cell flotation.
