According to the different associated minerals, fluorite deposits in the world can be mainly assorted into four types: quartz-type, calcite-type, barite-type and polymetallic symbiosis-type [].It is worth …
Wang et al. (2019) employed CA as a depressant to reduce the flotation recovery of Ca 2+-activated quartz. These findings indicated that CA could interact with calcium ions on Ca-bearing mineral surfaces and thereby has the potential to be used in the flotation separation of barite from fluorite.
The separation of quartz and kaolinite can then be performed. The tests and molecular dynamics verified that with the addition of Mn 2+, ... Yao et al. [23], [24], [25] studied the flotation separation of fluorite, scheelite, and calcite by Pb 2+ and Na 2 SiO 3 as well as Zn 2+ and Na 2 SiO 3.
In this study, the effect of water glass modulus ( n) on the separation of fine fluorite and quartz. was studied. The flotation tests on the single minera ls of fine fluorite and quartz (all less ...
The main purpose of fluorite flotation separation is to separate fluorite from symbiotic gangue ( such as quartz, calcite, barite, etc.), and also with some sulfide separation problems.
Fluorite is a crucial nonmetal F-bearing mineral that is the main source of fluorine element, and more than half of fluorite is used in the fluorine chemical industry [1], [2]. Fluorite is usually associated with barite, calcite and quartz minerals in …
It is known that the flotation separation of fluorite/calcite is extremely difficult because of their similar surface features. In this research, the combination of FeSO 4 ·7H 2 O and Fe 2 (SO 4) 3 (FF) as depressant for possible flotation separation of calcite/fluorite was systematically investigated, with sodium oleate (NaOL) as collector.

The separation of quartz and kaolinite can then be performed. ... Huang et al. [26] studied the separation of fluorite and calcite using Fe 2+ and Fe 3+ as inhibitors. They deduced that almost no Fe 2+ /Fe 3+ is adsorbed on the fluorite surface, and calcite reacts with it to inhibit the NaOL adsorption on its surface. Qin et al. [27] studied ...
The key technical problems of fluorite separation, such as flotation separation of fluorite and calcite, low temperature flotation reagents, and the influence of ions in pulp, were discussed. ... LIANG P M, YUAN Q Z, et al. Experimental study on flotation of a low grade calcite-quartz-fluorite ore[J]. Non-Metallic Mines, 2018, 41: 70 …
In the absence of fine quartz, fluorite exhibited a good flotation behavior with 91.6% recovery at the end of flotation. The result indicates that sodium oleate is an excellent collector for fluorite flotation. ... Use of Al 2 (SO 4) 3 and acidified water glass as mixture depressants in flotation separation of fluorite from calcite and ...
Nonetheless, bastnäsite is often associated with calcium-bearing gangue minerals such as fluorite, and the separation of bastnäsite from fluorite by flotation is usually difficult due to their similar surface properties and floatability ... Separation of feldspar from quartz using EDTA as modifier. Miner. Eng., 12 (1999), pp. 1393-1397.
Finally, the most widely seen fluorite-flotation cases, including separation of fluorite from quartz, calcite, barite, and sulfide, are summarized individually. The present review …
Fluorite ore, as an essential raw material in the fluorinated chemical industry, required effective separation and purification. The removal of impurities such as quartz becomes the key point in fluorite flotation.In this work, the fluorite flotation tests via adding the different mass ratios of metal ions (Fe 3+, Cu 2+, Al 3+) and sodium silicate …
The cassiterite occurring in hard-rock deposits is usually associated with polymetallic sulphide minerals and many other gangue minerals, including fluorite [1].The presence of fluorite makes the flotation separation of cassiterite a very challenging work because the conventional collectors for cassiterite also float fluorite well, such as fatty …
A series of flotation tests on single minerals in the Supplementary Material showed that using sodium oleate could achieve an efficient separation of fluorite from quartz (see Fig. S1). When sodium oleate was used alone, fluorite floated well with a recovery high up to 75% and quartz did not float, with a recovery near to 0.

Baryte ore is of great value due to its wide application in the fields of petroleum, chemical industry, medicine, etc. However, since barite is usually associated with salt minerals such as fluorite, calcite, quartz, etc., and has low grade, fine embedded particle size, and complex composition, it is difficult to achieve effective separation by …
The results indicated that the separation of fluorite and calcite was impossible in the absence of depressant due to the similar floatability.
