某些类型磷矿石常含有稀土、钍和铀等伴生元素。这种类型磷矿石具有较强的放射性,若直接将它制造磷肥施用,不但不符合综合利用的精神,而且施用这些磷肥所生长出来的农作物,对人体有害。因而必须经过选矿或其他方法将磷和稀土、稀有元素分离,方能达到变害为利、综合利用矿产资源的目的。本文就内蒙某地含稀土磷灰石矿进行磷和稀土分离及综合利用研究的情况作一介绍。
Some types of phosphate rock often contain rare earth elements such as thorium and uranium. Phosphorite of this type has strong radioactivity. If it is directly applied to the production of phosphate fertilizer, it is not only not in conformity with the spirit of comprehensive utilization, but also the crops grown from the application of these phosphate fertilizers are harmful to the human body. Therefore must be beneficiation or other methods of phosphorus and rare earth, rare element separation, in order to achieve the change for the benefit of the comprehensive utilization of mineral resources purposes. In this paper, a rare earth apatite mine in Inner Mongolia phosphorus and rare earth separation and comprehensive utilization of the study made an introduction.
