Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons.
Optimal fluorspar flotation was achieved under the following conditions: 3.6 g/kg of sodium oleate as the collector, 2 g/kg of sodium silicate as the pH modifier and depressant, a conditioning ...

Variables affecting froth flotation can be divided in two groups: chemical and physical. Reagents type and dosages take an important role depending on the ore type. Flotation of fluorite ores typically used tannings to depress calcite and ferrous minerals, starch and/or dextrin to depress quartz and a fatty acid collector [8, [16], [17], [18 ...

The Fe-oxide mineral liberation characteristics results indicated that 81.11% of the grains are full liberated, while 16.17% are the middlings and 2.72% locked in gangue. Based on the results and a requirement to make high iron grade pellets, reverse flotation method was selected for concentrating Fe in the fluorspar tails.
The beneficiation potential of fluorspar tailings to produce high grade haematite pellets was investigated. Detailed characterisation of the tailings was carried out, where physical, chemical, and mineralogical and liberation properties of the sample were determined, with the aim of selecting a suitable beneficiation technique.
The amenability of column flotation for the beneficiation of fluorspar was investigated, and the overall performance of the column flotation was compared to the performance of the existing conventional flotation cells at the plant. It was established that improved grades and recoveries could be obtained by adopting column technology. …

The most commonly used beneficiation process is froth flotation, producing fluorite concentrates of up to 99% purity. Typically, fatty acid is used as collector in fluorite flotation, and water glass as a depressant of silicate gangues; the ore pulps are heated to 35–85 °C in the system ( Crozier, 1992 ).
