Largest fluorite concentrate and briquette factory in Iran
Fluorite mines in Iran
According to the results of statistics of fluorite mines in operation, Iran ranks among the top 10 countries in the world and the first country in the region with a definite reserve of 2,307,700 tons and actual extraction of 77,000 tons and export of 2,363,000 dollars in 2019. Central Alborz region located in Mazandaran province and north of Semnan province has a special place in the country in terms of minerals. Among the provinces of the country, Mazandaran province has the highest production rate in terms of the number of mines in operation and some minerals such as fluorite. The number of operating licensed fluorite mines in this province is 14, half of which are currently active. Although Mazandaran province has the largest number of fluorite minerals in the country, geological evidence shows that the central Alborz fluorite metallogenic belt is among the three largest belts in the world. However, proper studies, design, and investment in relation to exploration, exploitation, ore preparation, and concentration, as well as processing and production of fluorite by-products such as hydrofluoric acid have not been done in this region.Fluorite processing
At present, special minerals such as fluorite are mainly used in the iron smelting industry after initial concentration and hand grinding, and some are used for export. If this mineral has important applications in various industries (especially chemical), it is necessary to convert its raw materials into raw materials that can be used in downstream industries and in the preparation and production of hydrofluoric acid. Fluorite is used directly or indirectly to produce products such as aluminum, gasoline, foam insulation, plastics, refrigerants, steel, and uranium fuel. The most commercial use of fluorite includes two types of acid grade or spar acid, which contains more than 97% calcium fluoride, and subacid grade, which contains 97% or less CaF2. The sub-acid grade is used for the extraction and melting of metals and ceramics and is usually known and read as metallurgical and ceramic grade or met spar.
