Bauxite, magnesia, fused a-lumina , and refractory clays in particular, have maintained China s strong position as the world ' s leading supplier of these minerals. However , important changes have taken place in the structure of Chinese and global supply of these minerals. More-over, the world refractory market and the minerals trading sector have also undergone a radical transformation that has influenced mineral supply, and shifted end product manufacture to China. This paper highlights these changes and sees hour they have, impacted on China as a world source of refractory minerals.展开更多
