Fluorite, also known as fluorspar, is a common non-metallic mineral resource, which is used in metallurgy, chemical industry, construction, optics and other industries. The common impurities in silica (SiO2) fluorite often affect the application value of fluorite, so it is necessary to remove silicon from fluorite beneficiation. So this article will introduce what are the silica-type fluorite beneficiation methods? Common silica-type fluorite beneficiation methods include flotation, magnetic separation, gravity separation, chemical separation and combined beneficiation.Details>>
The chemical formula of fluorite is CaF2. It is an important non-metallic mineral that can be widely used in chemical industry, metallurgy, building materials and other fields. Fluorite has low hardness, high density, strong fluorescence and other characteristics. However, fluorite often coexists with minerals such as quartz and calcite, and the ore properties are relatively complex. In order to obtain high-grade fluorite concentrate, a reasonable and efficient beneficiation process is essential. The fluorite beneficiation process process usually includes crushing, grinding and classification, flotation separation, roughing, scavenging and concentrating, concentration and dehydration, and tailings treatment.Details>>
Fluorite is the main raw material for the production of hydrofluoric acid, and hydrofluoric acid is the basic raw material for organic fluorine, which plays a vital role in the chemical industry. In many fluorite mines, it is often associated with barite. When the embedded particle size is coarse, gravity separation can be used to complete the separation, but when the particle size is fine, flotation separation is required. However, in conventional flotation processes, due to the similar floatability of fluorite and barite, flotation separation is very difficult. The role of reagents in the flotation process is crucial. The flotation reagents commonly used in fluorite flotation are mainly collectors and inhibitors. If the right reagents are selected, the flotation recovery rate of fluorite and barite can reach more than 80%.Details>>
Fluorite is an important mineral raw material in modern industry. It is widely used in metallurgy, chemical industry and building materials. Many developed countries even reserve it as an important strategic material. Fluorite is also called fluorite. With the rapid development of fluorine chemical industry and other industries, the demand for fluorite ore powder has been directly driven. From the properties of fluorite ore, flotation is often used as the main method in the ore dressing process. The principle process is mostly crushing and screening-grinding-ore dressing-dehydration process. Then this article will introduce its fluorite ore dressing process with a certain case!Details>>
As an important non-metallic mineral resource, fluorite is widely used in metallurgy, aluminum smelting, glass, ceramics, cement, chemical industry and other fields. Although my country has abundant fluorite resources, high-grade fluorite is rare and often coexists with quartz, calcite, barite, kaolinite and other minerals. Flotation is often the main method of mineral processing. When fluorite is flotated, the selection of reagents is particularly important. Then, this article will focus on introducing the commonly used flotation reagents for fluorite ore processing.Details>>
The main component of fluorite is calcium fluoride, which is an important mineral raw material for obtaining fluorine. Generally, pure fluorite is colorless, while common fluorites are in various colors, such as light green to dark green, blue, green-blue, yellow, wine yellow, purple, violet, gray, brown, rose red, dark red, etc. These fluorite ores often contain other gangue ores or metal ores, such as calcite, mica, etc. So when fluorite contains mica calcite, how to dress it? Let's take a certain mica calcite type fluorite ore as an example to introduce its fluorite beneficiation method.Details>>
Under the premise that the quantity and price of fluorite will rise throughout the year, the development of fluorite mines will be the focus of mining companies in 2024. As a common non-metallic resource, fluorite mines are not only used in metallurgy, building materials, ceramics, glass and other industries, but also follow the development of science and technology. Fluorite is gradually used in atomic energy, aerospace, medical and other industries, and its application range is becoming more and more extensive. Let's take a look at the fluorite ore dressing project completed by Xinhai in 2023!Details>>
In the flotation process, the selection of collectors is the key. Whether fluorite particles can be well collected is the key to improving the quality of fluorite concentrate. Therefore, this article will focus on the types of fluorite flotation collectors. Common fluorite collectors include fatty acids, modified fatty acids, combined collectors, and new collectors.Details>>

Quartz-type fluorite ore is mainly composed of fluorite (content up to about 85%) and quartz. At the same time, there are also small amounts of calcite, barite and sulfide. In production, quartz-fluorite ores are mostly rough-selected by grinding once, and the coarse concentrate is ground again for multiple selections. The pharmaceutical system often uses sodium carbonate as an adjuster to make it alkaline to prevent excessive amounts of water in the water. For the activation effect of valence cations on quartz, use fatty acids as collectors, add an appropriate amount of water glass to inhibit silicate gangue minerals, and control the amount of water glass (a small amount will activate fluorite, and an excessive amount of fluorite will will be suppressed).Details>>
