Abstract: China is rich in refractory raw materials，especially bauxite，magnesite and graphite， which play an important role in the world. Currently，Chinese government is paying more and more attention to resources and environment. The management of mining areas has been strengthened， and refractory raw material producers in China have also updated the environmental protection facilities and abandoned the backward production capacity，resulting in a shortage of raw material supply and a sharp rise in prices. The prices of main refractory materials，such as bauxite， magnesia，flake graphite and silicon carbide，fluctuate greatly，which have an important impact on the production of refractories. A favorable environment for the stable operation of refractory industry will be provided depending on more orderly mining operations in China，more complete supply chain of refractory raw materials，and the production lines of refractory materials with high automation degree and large-scale.
