Non-metallic mineral resources for metallurgy

1. Magnesite  

According to Geology and Mineral Resources Ministry data, in 1996, China has a total magnesite ore production mining at 254, distributed in Liaoning, Gansu, Shandong, Hebei and Henan provinces, the total production capacity of 9,548,000 t of ore / a, among a number of state-owned enterprises 8, The actual production capacity of 3.148 million t ore / a. There are 246 non-state-owned production mines with an actual production capacity of 6.4 million tons of ore /a . In 1996 , the country's total annual output of magnesite was 7.4 million tons , of which non-state-owned small enterprises accounted for more than 80% . Most of the magnesite is used as a refractory in the form of magnesia, and a small part is used in building materials. High value-added products include calcined magnesium, light burnt magnesium, fused magnesium, fused magnesia (EFM) , high grade burnt magnesium (DBM), and magnesia- graphite refractory bricks. Magnesite is one of the dominant minerals in China, and its reserves, production and export volume rank first in the world.

Second, fluorite

In 1996 there were 072 to produce one fluorite mine, mainly in Zhejiang, Jiangxi, Inner Mongolia, Fujian, Hubei and other provinces, state-owned and other economic class and medium-sized mines produce 76, the actual production capacity of 1.689 million t ore / a , 996 non-state-owned small-scale production mines , the actual production capacity is about 4.23 million tons of ore / a , the national fluorite mine output is about 6 million tons , and its Chinese enterprises account for 36% of the mines , the main products are fluorite blocks, fluorite powder, etc. . China's output and exports are both ranked first in the world.

Third, refractory clay

In 1996 , there were 714 refractory clay production mines in China, mainly distributed in Shanxi, Shandong, Hebei, Henan, Sichuan, Jilin, Hubei, Xinjiang and other provinces ( regions ) , with a total production capacity of 6.63 million tons of ore /a , and its economy in China and other economies. There are 40 large and medium -sized production mines and 674 non-state-owned small production mines . Refractory clay is often used as a raw material for shaped refractories and amorphous refractories.
