Fluorite classification application

萤石是一种由钙和氟（CaF2）组成的工业矿物。鉴于其在各种氟化工、冶金和陶瓷、建材中的广泛下游应用，它是所有工业化国家的关键商品。

萤石有两种不同等级的产品：

Acid grade fluorite – a high-purity material used in the chemical industry, containing over 97% calcium fluoride and mainly used for the production of hydrofluoric acid.

Hydrofluoric acid is an important intermediate in the fluorine chemical industry, mainly used in the production of fluorine chemical products, including refrigerants, aluminum fluoride, fluorine-containing polymers (fluororesins, fluororubber, fluorocoatings), electronic grade hydrofluoric acid (semiconductor cleaning agents), fluoride salts, etc. The fields involving new materials and new energy, such as fluoropolymers, fluorinated fine chemicals, and fluoride salts, are developing rapidly, and the proportion of consumption is expected to increase in the future.

冶金级萤石--含有75%以上的氟化钙。这种材料大部分用于生产铁、钢和其他金属。萤石可以作为助熔剂，从熔融金属中去除硫和磷等杂质，提高炉渣的流动性。每吨金属生产需要9至27公斤的萤石。

High grade fluorite ore – containing over 65% calcium fluoride. Widely used in metal smelting, ceramics, cement production, and other industries. The production of these fields requires a stable source of calcium fluoride, and high-grade fluorite ore perfectly meets this demand. As an “industrial monosodium glutamate”, the value of fluorite lies not only in its chemical composition, but also in its strategic position as the cornerstone of fluorine chemical industry. With the rise of emerging industries such as new energy and semiconductors, the demand structure of fluorite will continue to optimize, promoting the industry to extend towards high value-added fields.
