In the production of commercial grades of ore, such as acid-grade fluorspar, it is necessary to concentrate the fluorspar and remove substantial quantities of the gangue materials.
Fluorite (fluorspar), an important industrial mineral ore, is one of the major raw materials for the production of hydrofluoric acid. Naturally occurring fluorite ore contains gangue minerals, primarily silica (SiO 2) and calcite (CaCO 3 ). The beneficiation of fluorspar is needed to mitigate the severity of operational issues.
Fluorite, also known as fluorspar, has a main chemical composition of CaF2, a relative density of 3.0-3.

A combination of flotation-beneficiation and pyrohydrolysis is applied to recover and to liberate the flourine. Flotation of a finely locked high-calcite fluorspar ore containing only 11.7% CaF2 recovered over 92% of the fluorspar at a grade of 51-52% CaF2.
Various iron ore samples drawn from different mines and their mixtures were subjected to the test work. Results of pilot scale tests clearly indicate the superiority of flotation column vis-a-vis conventional cells and dual extraction column.
To ensure a consistent feed grade to the beneficiation facility, fluorspar ores are typically mixed before use. Most ores require crushing, washing, and screening before processing, while exceptionally high-grade fluorspar can be exported immediately from the screening stage.

This is carried out by the processes of beneficiation of the iron ore. Beneficiation of the ore is the process where ore is reduced in size and gangue is separated from the ore. Since each of the iron ore deposit has a unique mineralogy, the beneficiation process is specific to each deposit.
At present, the primary beneficiation approach of fluorite is flotation [ 5 ]. In the deposits, fluorite is often associated with gangue minerals such as calcite and quartz, which share similar surface properties with fluorite (i.e. solubility, crystal structure, hydrophobicity, and zeta potential), making the effective separation challenging to …
