利用干式磁选工艺回收铁矿石资源的试验研究

Test on Recovery of Iron Ore Resource by Dry Magnetic Separation Process

大孤山铁矿在矿体深部矿岩分界线处多个采矿部位出现低品位矿石或混岩,因为综合品位低,无法进行利用,只能作为岩石抛弃,造成矿石资源的流失和浪费。本试验探讨用干式磁选工艺从排岩中回收铁矿石的可行性,对于回收铁矿资源、降低采矿生产成本、提高资源利用率、保护环境具有重要意义。

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.
