Sources and availability of raw materials for fluorine chemistry

The two most important sources of fluorine are the minerals fluorite, commercially known as fluorspar, and fluorapatite, commercially known as phosphate rock. The major consumers of fluorspar are the aluminum, chemical, and steel industries. Acid-grade fluorspar, one of three commercial grades, is used primarily to make hydrogen Fluorspar Production from industrial flotation process; The procedure starts with the extraction of the fluorspar-containing mineral ore from the veins of other ores, including slate, gneiss, limestone, etc. The recovered material is subsequently processed through crushers to get fine powder-like materials.Fluorspar Prices: Latest Price, Pricing, News, Market Analysis

Fluorite Mining Processing Equipment Flow Chart Cases

Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons.Fluorite is a nonrenewable mineral used to produce anhydrous hydrofluoric acid (AHF) and aluminum fluoride. The demand for low-grade fluorite powder (CaF2 < 97%) has fallen sharply owing to the current market conditions. Therefore, a large number of fluorite concentrates have been improved by acid leaching. While this approach can Clean and Feasible Utilization of High Silica Fluorspar

For instance, a novel combined collector has been utilized to beneficiate the fluorspar ore in the Fenglin plant, China. The commercial name of this collector is GY-2, which is composed of sodium naphthenate, fatty acid, and water. Tannin (tannin extract) is a macromolecular amorphous substance extracted from the roots and shells of some29.2 Fluorite ore deposits. The main fluorite-containing mineral is fluorspar, CaF2. In its pure form it contains 51.5% calcium and 48.9% fluorine, and has a specific gravity of 3.18. The hardness is about 4. Commonly it is glassy, colorless, white, or grayish.
