Fluorite has an extensive range of colours such as blue, green, pink, purple, and yellow. It is an attractive and striking stone because habitually more than one shade takes place in such a single stone. In fact, the earliest Egyptians use this stone to shape out statues and scarabs, which most Chinese has utilized it for carvings more than 300 ...

29.2 Fluorite ore deposits. The main fluorite-containing mineral is fluorspar, CaF2. In its pure form it contains 51.5% calcium and 48.9% fluorine, and has a specific gravity of 3.18. The hardness is about 4. Commonly it is glassy, colorless, white, or grayish. It can be also purple, pink, blue, green, or yellow.

At higher temperatures the fluorine becomes volatile and is released as a poisonous gas. This happens as O 2 combines with CaF 2 to produce CaO and F 2 gas. Even if the gas can be tolerated, the material slowly decomposes to evolve the fluorine gas, and thus is troublesome for use in glazes because of the blistering problems. If fluorspar is ...

The Vergenoeg Fluorspar Mine is in Limpopo, South Africa. Production output of the Vergenoeg Fluorspar Mine was considered to be small size. The ore mined is composed of hematite and fluorite with waste material consisting primarily of feldspar. The ore body is described as tabular shaped and is found 30 meters (98 feet) below the surface.

Where those metasediments contained potash feldspar, the fluorite concentrates have elevated silica contents due to the presence of binary locked potash feldspar-fluorite particles. Thus, the potential for silica beneficiation problems can be predicted by recognizing that the fluorite ores have replaced marbles and, especially, biotite schist. 10

Fluorite or fluorspar is the mineral form of calcium fluoride (CaF 2).The mineral may occur as massive (Fig. 1.15) or vein-type deposit, in association with metallic minerals forming a part of mineralization.The associated minerals include barite, calcite, quartz, galena, sphalerite, and pyrite (Fig. 1.16).The vein-type mineralization is of hydrothermal origin.

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.
