Introduction

Fluorite (Fluorite), also known as fluorspar, is a mineral, its main ingredient is calcium fluoride (CaF2), containing impurities, Ca is often replaced by Y and other rare earth elements, such as Ce substitution. Its chemical component also contains small amounts of Fe2O3, SiO2 and a little of Cl, O3, He, etc. Natural fluorite often has significant bright colors, lower hardness than a knife. It can be used in the preparation of hydrogen fluoride: CaF2 + H2SO4 = CaSO4 + 2HF ↑; artificial fluorite technology is not yet mature in front, is the manufacture of optical glass lens materials.

With fluorite ore mining, high-quality fluorite ore less and less, but smelting industry for high-quality fluorite ore demand has grown, so fluorspar derivatives was born.

The main purpose

Metallurgical grade fluorite ball is to solve the smelting process breathable, environmentally friendly, easy to manipulate and low phosphorus special requirements, which is made of metallurgical grade fluorspar powder plus inorganic adhesive. It replaces the fluorite ore is widely used in steel smelting, non-ferrous metal smelting, ferroalloy smelting of iron craft production and other industries.

In the aluminum industry, CaF2 can be used for the production of aluminum fluoride, hydrofluoric acid, synthetic cryolite, sodium fluoride and magnesium fluoride.
