Recently, the Ministry of Land and Resources issued the “Notice of Controlling Total Quantity of Mining Fluorite Mines for High Alkaline Clay Mines in 2010†(hereinafter referred to as the “Noticeâ€). In 2010, the national total control index of high-alumina clay mining was 4.5 million tons.
(Amount of ore), total control of fluorite mining is 11 million tons (ore).
This is the first time China has carried out the total mining control and management of high-alumina clay and fluorite mines. It is also controlling the mining of mineral resources this year after the Ministry of Land and Resources controls the total mining volume of tungsten ore and rare earth minerals. .
The "Notice" stated that the administrative departments of land and resources of all provinces (autonomous regions and municipalities) must decompose and issue the general indicators, and report the implementation of the indicators and the list of companies after the public announcement by the end of May. The "Notice" stated that, in principle, applications for the registration and exploitation of new high alumina clay and fluorite mines will no longer be accepted.
On January 2 this year, the General Office of the State Council promulgated the "Circular on the Implementation of Comprehensive Measures to Control the Mining and Production of Refractory Clay Fluorite", announcing the regulation and improvement of the exploitation, production and export of fire-resistant clay and fluorite. Tax rate.
The "Notice" also requires that high-alumina clay and fluorite ore mining companies should report their production quantities, sales volume, sales targets, etc., to the local land and resources management department on the 2nd of each month; the provinces (autonomous regions and municipalities) The Resources Department shall send the Ministry of the Ministry of the implementation of the first quarter of the first four days of each quarter.
The use of high alumina clay:
The main minerals of high alumina clay are diaspore, boehmite, gibbsite, and kaolinite. Since the content of AL2O3 is higher than that of ordinary fire-resistant clay, its hardness and specific gravity are relatively large, and its refractoriness is high. It is often used as a high-grade refractory product. It is one of the important minerals in Shanxi, and it is also one of the minerals in the county that has a certain potential prospect. It is mainly produced in the lower iron-aluminum section of the Lower Carboniferous Central Benxi Formation, and is often co-bearing with bauxite, ordinary refractory clay, and Shanxi-type iron ore, forming a unique metallogenic series in North China.
The use of fluorite
The use of fluorite is very extensive. With the advancement of science and technology, the application prospects are more and more broad. Currently used in the metallurgical industry to produce raw materials for aluminum cryogenic cryolite, hydrofluoric acid produced in the chemical industry, raw materials for various fluorinated salts and refrigerant freon, building materials industry as decorative materials, followed by light industry, optics, and engraving And defense industry. Therefore, according to application requirements, currently China's fluorite mineral products mainly include four major series, namely, fluorite block minerals, fluorspar (fluorine) mineral concentrates, fluorite powder minerals, and optical and fluorite-engraved fluorite.
