Fluorite ore beneficiation is a complex process involving various stages of extracting the fluorspar mineral from its original form. The process typically involves crushing, grinding and flotation methods to separate valuable fluorspar from other impurities. An interesting aspect of fluorspar ore beneficiation is the use of advanced …
Given the similarity of the surface properties of calcium-containing minerals, the flotation separation of fluorite, scheelite, and apatite from calcite becomes unusually difficult when fatty acid is used as collector (Hu and Xu, 2003). The flotation separation of calcite with other calcium-containing minerals has been extensively investigated.
