As a rare and non-renewable strategic non-metallic mineral resource, fluorite has been widely used in many fields such as national defense, chemical industry, metallurgy, optics. Fluorite resource reserves are abundant in China, but there are many lean ores with complex composition and low recovery. This study summarizes the reserves, distribution, metallogenic …
Therefore, fluorite ores usually need beneficiation and the most efficient strategy is froth flotation . Usually, SO is the most widely used collector for fluorite flotation due to its good collecting ability . It is noted that many fluorite beneficiation plants are built in areas with relatively cold temperatures, where the temperature of ...
In this study, a novel scheme for fluorspar beneficiation was investigated for the floatation of fluorite and depression of calcite and other gangue minerals simultaneously without the use of ...
To address the growing demand for fluorite, improving or developing beneficiation technologies for low-grade and associated fluorite ores is an important direction in fluorite production [6], [7]. Calcite is a prevalent gangue mineral in fluorite ores [8], [9], with flotation serving as the predominant industrial technique for separating ...
Froth flotation is considered as the most effective method for the beneficiation of fluorite (Foucaud et al., 2018a, Zhang et al., 2018). For fluorite-quartz or fluorite-sulfides type mineral deposits, the flotation separation of fluorite from associated minerals is relatively easily achieved by using fatty acids or xanthates as collectors.
Fluorite is commercialized as metallurgical- or acid-grade depending on its purity (Eurofluor, 2016, Hayes et al., 2017). ... flotation, magnetic, and gravimetric separation are the most common physical beneficiation processes employed in conjunction with chemical leaching to pre-concentrate minerals from different deposits, including ...
Fluorite ore beneficiation methods mainly include manual selection, gravity separation, and flotation. Manual selection is often used as an auxiliary method. Gravity selection is suitable for metallurgical-grade lump ore production or as a pre-selection operation for the fluorite flotation process. The flotation effect of fluorite can be ...
Fluorite is widely associated in rare earth ores, and the utilization of associated fluorite has become an important research direction of the comprehensive utilization of rare earth resources.

Fluorite is a non-metallic raw material with strategic significance, mainly used in the three major industries of metallurgy, chemical industry and building materials, followed by light industry, optics, sculpture and national defense industry. In production practice, the beneficiation methods of fluorite ore mainly include hand separation, gravity separation and flotation.
Fluorite beneficiation is a process that aims to remove impurities and enhance the quality of fluorite ore, ultimately increasing its value and suitability for different applications. By …
The most commonly used beneficiation process is froth flotation, producing fluorite concentrates of up to 99% purity. Typically, fatty acid is used as collector in fluorite flotation, and water glass as a depressant of silicate gangues; the ore pulps are heated to 35–85 °C in the system ( Crozier, 1992 ).
At present, the primary beneficiation approach of fluorite is flotation [5]. In the deposits, fluorite is often associated with gangue minerals such as calcite and quartz, which …
