World supply of refractorygrade bauxite is fairly limited, particularly for the export market. The main producers of refractory bauxite are based in China, and the country accounts for over 85% of production. Leading companies include Bosai Minerals, Shanxi Fangxing, CMP, and Shanxi Yangquan.
The bauxite found in China, with the mineral feature of diaspore, characterized by highaluminum, highsilicon, and low ratio of Al 2 O 3 /SiO 2 (Al/Si), is an important raw material for the refractory industry and a strategic resource .

Synthetic mullite results from four main heating processes: (1) melting of alumina and silica or bauxite and kaolin in an electric furnace at 1,914°C; (2) sintering alumina and kaolin, bauxite and kaolin, or alumina, kaolin, and kyanite above 1,763°C; (3) calcining kyanite at 1,300°C; or (4) sintering a siliceous bauxite or mixtures of bauxite and kaolin at about 1,561°C.
It is found that when a sulfuric acid ( mol/L) to bauxite ratio of 9 mL/g and a temperature of 70 °C and a residence time of 2 h are used, the potassium and ironremoving efficiency from the bauxite calcined at 550 °C can reach % and %, respectively, and the treated bauxite can be used to produce homogenized bauxite.
