Froth flotation of fluorite: A review - ScienceDirect

2021-4-1  The best pH for fluorite flotation in either pure water (collectorless flotation) or in the presence of surfactants (froth flotation) ranges from 7 to 11 [, , , ]. It was also shown that pH 9 is usually selected as the most suitable pH regardless of flotation reagents [54,55]. This pH value corresponds well to the zero charge point of fluorite.

2021-11-12  Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

2021-12-4  Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Another important factor in mineral beneficiation processes is the equipment design. In froth flotation both cells and columns are used. The column flotation stands out for its high efficiency in fine particles (slimes), its low cost of construction and assembly [15,16]. Due to this fact, it is crucial to compare how fluorite flotation behaves ...

Selective flotation separation of fluorite from calcite by ...

Micro-flotation experiments indicated that SG could efficiently realise the flotation separation of fluorite from calcite. Laboratory-scale flotation tests showed that good beneficiation indices with CaF 2 grade of 76.15% and CaF 2 operating recovery of 96.23% of rough concentrates were obtained by adding 100 g/t SG at pH 9.

Comparison Between Performance of Fluorite Flotation

Fluorite is an important industrial mineral composed of calcium and fluorine (CaF2). This mineral is widely distributed through different deposits. However, in most cases, fluorite is tightly associated with gangue, such as calcite and quartz. In this paper, different depressants are tested in the flotation of fluorite in two different laboratory configurationsmdash;cell and column.
