FLUORITE - FLUORSPAR

FLUORITE - FLUORSPAR

Fluorite (also called fluorspar) is a mineral composed of calcium fluoride, CaF2. The name is derived from the Latin word “fluere” meaning “to flow” because it melts very easily to a free-flowing liquid. In fact, the name of the element fluorine is named so because it is a major constituent of fluorite. Fluorine is widespread in different compounds but not found in Free State due to its strong chemical affinity.

AMMD FLUORITE PRODUCT

We are pleased to inform you that Our Company, Asia Mines and Minerals Development Co., is professional supplier and exporter in the field of mineral product like Fluorspar from IRAN origin. Our fluorite product categorized as below:
Acid or chemical grade:
This grade of fluorite ideally contains a minimum of 97% CaF2 and up to 1.5% SiO2. For ordinary products, however, 93% CaF2 is acceptable as in Iran.
Ceramic grade:
For high-quality ceramic products, fluorite containing a minimum of 95% CaF2, up to 2.5% SiO2 and up to 1.5% CaCO3 is generally considered standard in Iran. But strictly speaking, there is no standard grade and it is highly variable depending on the quality of the finished product, and for very ordinary cheap products, low-grade fluorite can also be used.
Metallurgical grade:
This grade is expressed in terms of what is called effective units of CaF2. Effective CaF2 is determined by subtracting 2.5 units for every unit of SiO2. Determined thus, the effective CaF2 be at least 60 percent, which is the same as 80% CaF2 and 8% SiO2. But the maximum grade can go beyond 97% CaF2 with a maximum of 1% SiO2.

USES AND SPECIFICATIONS

Fluorite has few primary uses, one of which is hydrofluoric acid. There is a number of uses of this acid and its derivatives. The principal uses are therefore grouped under those based on the primary mineral fluorite, those on its principal derivative hydrofluoric acid, those on the latter’s derivative fluorine gas and those based on a mix of these. They are:

A. Uses based directly on fluorite
1. Flux in metallurgy
2. Ceramics
