Separating fluorite from quartz and calcite by forth flotation can be both in weak-acidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO4 can decrease the depression that water glass works on the fluorite, and acidized water glass has a selective inhibition on the silicate minerals. The close flowsheet protocolled in the experiment can ...

Quartz and fluorite are two very different minerals, each with a different hardness and crystal structure, although on the surface they look very similar. Both rocks come in clear or white tones, as well as purple, pink, blue and green. The visual similarities make them difficult to tell apart, but you can ...

sulphide ores [13], especially for the flotation of fluorite [7]. However, the flotation separation of fluorite from quartz using water glass is not so effective, as there is always a small amount of fine quartz (less than 10 m) in the fluorite concentrate. The floated fine quartz in fluorite concentrate has been reported to be the result of ...
The phosphate rock was found to be formed by carbonate fluorapatite, calcite, dolomite, natural gypsum, quartz, calciteMg, apatite, pyrite, fluorite, and sphaleriteCd and phosphogypsum by synthetic gypsum and sphaleriteCd. >>Price; phosphate rock beneficiation plant inovavloerverwarming.

Fluorite is the principal mineral of fluorine and usually coexists with quartz in deposits. The removal of fine quartz in fluorite concentrate is the main problem in fluorite flotation. In this study, the flotation tests on fluorite, quartz and a weight equivalent mixture (all less than 10 μm) using water glass (with different modulus) as depressants and sodium oleate as collector were conducted.
These purple fluorite crystals rest on quartz, partially covered by calcite. The specimen is from the Xiayang, Yongchun County, Quanzhou, Fujian, China. This piece measures 9.5 cm wide by 7.4 cm tall by 4.1 cm front to back. There is damage to a couple of the quartz crystals.

Ca-containing gangue minerals such as luorite, Calcite have same F surface activity point--calcium ions and approximate flotability with scheelite, it is difficult to achieve good dressing index of rough a concentrate of scheelite.
Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly ...
Fluorite mineral is one of common non-metal minerals, which is also called CaF2. Fluorite mineral has rich colors. It is important fluoride minerals for the industry. Fluorite mineral common grows with calcite, dolomite, quartz, barite, pyrite, galena, blende and so on.

Quartz Inclusions: Fluorite. Calcium Fluoride (CaF2) can be found in any colour but when formed within quartz the blue and purple colours are more common. Growing as a cubic material, fluorite usually forms as cubes or octahedrons with strong colour zoning throughout the crystal. Fluorite in quartz…
