Zhongang Mining: a new and active application field of fluorite resources

Fluorite is a valuable mineral resource in China , Because of its non renewable nature , As early as 2016 It was listed in the national strategic mineral list in . At the same time, in view of the domestic mining intensity and intensity of fluorite resources , China has successively issued a series of protective policies to support , Environmental protection 、 Safe production 、 The construction of green mines and the demarcation of ecological red lines are becoming more and more strict , Industrial policies are gradually tightening 、 Supervision has been strengthened , The entry threshold is getting higher and higher . therefore , From the supply side , It is difficult for the mining and production scale of a single fluorite mine to grow on a large scale , However, the supply of comprehensively recycled fluorite will increase significantly .

And the demand side , First , Fluorine chemical industry has a large demand for fluorite downstream . The founding of new China 70 Since then , China's fluorine chemical industry has been growing , To form the 1000 Many enterprises 、 The total annual production capacity exceeds 500 Ten thousand tons of 、 Annual sales over 600 Billion yuan , Production capacity and consumption account for 50% above , It has become the second in North America 、 The European 、 Fluorine chemical production after Japan 、 Big consumer countries . Formed in Zhejiang Juhua 、 Sinochem blue sky 、 Zhejiang Sanmei 、 Shanghai sanaifu 、 Shandong Dongyue 、 Multi fluorine multi chemical industry 、 Jiangsu Meilan and other key enterprises are nearly 20 A number of .

Fluorine containing refrigerants are the main application fields of fluorine-containing chemical industry . With the gradual transition of fluorine refrigerant from the second generation to the third generation in China  HFCs（ Hydrofluorocarbons ） Class and the fourth generation  HFOs（ Fluoroolefins ） Class refrigerant , The fluorine content of the new generation of refrigerants has increased significantly , The demand for fluorite in the upstream will increase steadily .

secondly , Another important use of fluorite is as a flux in the steel industry , It is mainly used in hot metal pretreatment 、 steel-making （ Roughing ）、 There are three stages of secondary molten steel refining , Generally, the amount of steel fluorite used per ton is  1.5-8  kg . With the steady growth of crude steel production , The demand for fluorite has also increased .

In addition, in addition to the traditional application of fluorite, steel 、 Electrolytic aluminum 、 cement 、 The overall demand for glass is still stable . meanwhile , The new application fields of fluorite are expanding ：（1） In the new energy industry , Fluorine containing materials play an indispensable role , The main products include lithium battery material lithium hexafluorophosphate 、 Aluminized borohydrofluoric acid electrolyte 、 Fluorine containing solar cell back film with excellent performance 、 High purity hydrofluoric acid for solar panel cleaning and glass carving ;（2） In the new material industry , Organic fluorine materials have excellent properties Good chemical resistance 、 Thermal stability 、 Dielectric 、 Non combustible, non viscous and other excellent properties , It is widely used downstream .

From the perspective of market supply and demand as a whole , Reduced by advantageous resources 、 The pressure of environmental protection supervision is rising 、 The increase of mining costs and the adjustment of national policies , China's Fluorite production has not increased significantly , But demand is growing , Make the whole market in short supply , As a result, the import volume of domestic fluorite has increased greatly .

At present, the most urgent thing is to explore fluorite resources , Investment in exploration , Provide support for the large supply and reserve of fluorite resources . Zhongang mining, as a member of Fluorite Mining Enterprises , It contracts two mines under exploitation , Continue to contribute to the export of fluorite resources .
