Abstract: The low grade ore or rock-mixed ore occurring at several points on the ore-rock boundary at depth in Dagushan Iron Mine can not be recovered due to the low comprehensive grade, and have to be discarded as rock, leading to the loss and waste of the ore resource.This research is carried out to exploit the feasibility to recover the iron ore by dry magnetic separation process, which is of great importance to the recovery of iron ore resource, reduction of the mining production cost, raising the resource utilization rate and environment protection.
