Popis:	China, the largest aluminium producer, is seriously lacking of bauxite reserves. However, there are more than 200 million tons high iron diasporic bauxites cannot be properly utilized because there is no technical and economically viable technology. The medium temperature metal-based roasting technology will hopefully solve this problem. The grain growth mechanism of iron minerals, the influences of roasting temperature, roasting time, coke dosage, grinding fineness and magnetic field intensity were studied respectively. In comparison with high temperature smelting process, the energy consumption is lower. The iron minerals and bauxite in the ore are utilized effectively, and the results are desirable.
