Anionic flotation is the most efficient method to separate fluorite from barite in mineral processing while the critical point of successful separation lies on the depressant.
Bastnaesite is a chief natural source of light rare earth elements (LREEs). The effective depression of Ca-containing minerals such as fluorite and calcite in bastnaesite flotation system is normally difficult, and it is imperative to exploit more environmentally-friendly depressants which can inhibit these gangue minerals simultaneously. Hence, we employ citric acid (H3Cit), a ...
The separation of barite from fluorite (and calcite) can be realized by adding >3 × 10 −5 mol/L sodium fluosilicate to depress the barite and to float fluorite. This developed flotation separation process exhibits a great potential for industrial application.
Fluorite ore is brittle and fragile. It is easy to produce many high-grade powdery ores during crushing, and there will be some loss in the process of gravity separation and manual separation. Therefore, the gravity separation and manual separation of fluorite ore tailings are often go to the flotation process to improve the concentrate grades.
Fluorite flotation process is suitable for high silt content, impurities mineral and fluorite symbiose, fine disseminated grain-size, etc complex ore property and difficult separation fluorite ore. Fluorite flotation method The main problem with fluorite is the separation from symbiotic gangue (quartz, barite, etc.).

fluorite ore :The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good.
The flotation experiments were conducted to evaluate the separation efficiency of the two minerals, and the results showed that cassiterite and fluorite could be efficiently separated at the ...
Apr 01, 2021· It prohibits fluorite flotation at pH = 6, and thus benefits the reverse flotation. Fluorite can be activated at pH = 8, and then enriched by flotation. Thus, pH is the key parameter controlling the efficient separation. However, the cost of organic phosphonic acid is relatively high, limiting its application in industry.
However, Flotation separation of scheelite from fluorite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics such as solubility, hardness, specific gravity, and PZC (point of zero charge) [2]. Flotation techniques have been extensively applied to separate scheelite and fluorite.
