Abstract
Aiming at the disadvantages of traditional magnetic roasting process, suspension calcining process was suggested to dispose refractory iron ore. The experiment indicated that under the conditions of 750°C~850°C, CO volume percentage was 1%, the limonite and siderite could efficiently transformation into magnetite, which only needed 10~20 secs. Tests of roasting-magnetic separation could attained results as: concentrate iron grade be 49.26%, recovery of iron be 87.28%.
