Get PriceHydrofluoric acid Fluorspar is widely used in the manufacturing of hydrofluoric acid or HF (52% of its end use) which serves as feedstock for many different chemical processes. Hydrofluoric acid from fluorite (acid grade) is used in the synthesis of fluorocarbons (CFCs, HCFCs, HFCs) or fluorine-bearing chemicals such as
Get PriceGlobal Acid Grade Fluorspar Powder Market is expected to grow at a CAGR x.x% over the next ten years, and will reach at US$ XX.X Mn in 2029, from US$ XX.X Mn in 2019
Get PriceHydrofluoric acid is manufactured by the heatingacid grade fluorspar (CaF2) with liquid sulfuric acid, forminggaseous hydrogen fluoride andsolid calcium sulfate as by-product. The endothermic reaction usually takes place in a rotary tube furnace. The entire process is kept under vacuum to help pull off the product gases and to promote HF production
Get PriceFluorspar is the predominant commercial source for the chemical element fluorine. Fluorine is a non-metallic element and the lightest of the halogens and therefore largely irreplaceable in its use. There are two principal commercial grades of fluorspar: Metallurgical grade (60-96% CaF2) and acid grade .
Get PriceCommercially available Fluorspar contains about 0.8 to 1.5% Si02 plus minor trace impurities. The product is minimally hazardous when in its delivered state combined with about 10% maximum water as a filtercake. Dust hazards exist when the product is either dried .
Get PriceFluorine is the most chemically reactive element and world fluorspar demand is dominated by the chemical industry. This dominance is expected to continue throughout the outlook period to 2022. All fluorochemicals are derived initially from the manufacture of hydrofluoric acid (HF), itself produced from acid-grade fluorspar (acidspar).

[PDF]Get PriceAcid- or ceramic-grade fluorspar also may be used to manufacture enamels, glass and fiberglass, and welding rod coatings. Metallurgical-grade fluorspar is consumed mainly in steelmaking, but is also used in making portland cement and casting iron and steel.
Get PriceFluorspar (20-80% calcium fluoride) is concentrated to 98% purity by flotation techniques to obtain 'acid-grade' material. Silica is the principal impurity removed. The acid-grade fluorspar is mixed with preheated concentrated sulfuric acid and the resultant slurry is fed continuously into large, rotary kilns.
Get PriceFluorspar is used directly or indirectly to manufacture products such as aluminum, gasoline, insulating foams, refrigerants, steel, and uranium fuel. Byproduct fluorosilicic acid production from some phosphoric acid producers supplements fluorspar as a domestic source of fluorine, but is not included in fluorspar production or consumption calculations.

Get PriceCeramic grade fluorspar has applications in the production of ceramics, specialty ware, and enamel ware. Others segment, such as optical grade and lapidary grade, held minimal share of the global fluorspar market in 2016. Application-wise, hydrofluoric acid contributed to 40% share of the demand in the global fluorspar market.
Get PriceFluorspar is also produced in Spain, Kenya, Namibia, Morocco, Kazakhstan and Brazil. Acid-grade Chinese fluorspar contains less than 1 percent silica, and due to its lack of impurities is one of the most desirable types of fluorspar. Mexican acidspar is higher in arsenic.
