宜昌丁东低品位磷矿可采厚度之探讨

Discussion on minable thickness of Dingdong low-grade phosphate ore in Yichang

宜昌丁东磷矿采用房柱法回采,重力选矿。针对矿体的赋存特征,为了使采出的矿石能够满足选矿工艺对入选品位的要求,在设计开采方案时,对几种矿层的可采厚度进行了计算。

Yichang Dingdong Phosphate Mine adopts mining process of room-pillar and beneficiation process of gravity separation. In the process of the design of the mining process, some minable thicknesses of the different phosphate bed were calculated based on occurrence characteristic of the phosphate body to make the ore mined meet requirement of gravity separation.
