Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

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.

Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks. Visit gemdat.org for gemological information about Fluorite.
The Processing Line of Fluorite. In general, fluorite processing includes crushing, screening, grinding and other processes.Because it always contains some impurities, so it is necessary to add beneficiation at last if you want to obtain high purity fluorite powder. …

Fluorite ore has a specific gravity of 3.0-3.3 and good natural floatability. The mainly separation method is flotation and gravity separation. The flotation method is mainly used to produce high-quality chemical grade fluorite powder; the gravity separation method is mainly used to produce coarse-grained metallurgical grade fluorite concentrate.
Disclosed is a novel fluorite purification method which can particularly reduce the content of arsenic in fluorite effectively. As is leached from a fluorite raw material containing CaF 2 and As by acid leaching (or mechanochemical acid leaching) in the presence of an acid while fracturing the fluorite raw material, thereby producing purified fluorite having a reduced arsenic content.
A great deal of research and production practice shows that flotation is a useful method for recovering fluorite ores, suit for large scale fluorite ore processing, the beneficiation method( flotation process and chemical agent) varies from the ore characteristics. if you need a fluorite ore flotation machine, pls contact us.

An improvement of the ionic conductivity has been reported when mixing two fluorite-types compounds: CaF 2 –SrF 2 [65] or BaF 2 –CaF 2 [66]. Especially for the mixture CaF 2 with BaF 2 by ball milling, Düvel et al. [67] obtained a metastable solid solution with a fluorite structure demonstrating a much higher conductivity than ball milled ...
