Based on the current situation of a large number of high ferrous bauxite existing in China, the process of low temperature magnetization roasting-magnetic separation to high ferrous bauxite was carried out. The influences of roasting temperature, roasting time, coke dosage, magnetic field intensity, feeding time and liquid-to-solid ratio were studied, respectively. In comparison with high temperature smelting process, the energy consumption was greatly reduced. At the same time, the iron and aluminum in the ore were utilized effectively and the results were desirable.
