磷矿是一种具有有限性和不可再生性的战略资源。我国磷矿资源丰富,储量较大,分布集中。但是随着富矿资源的日渐被开采殆尽,磷肥的生产以中低品位磷矿为原料是该行业的发展趋势。中低品位磷矿中又多含稀土元素,稀土是重要的战略资源,因此国家相关规定开采中低品位磷矿时需同步提取稀土元素,从磷矿回收稀土资源和磷资源,回收价值可观。既实现了资源的可持续发展,又为社会带来效益。由于目前对磷矿中稀土缺乏成熟的工业化应用技术,因此限制了该类矿石的开采。
Phosphate is a limited and non-renewable strategic resource. China is rich in phosphate rock with large reserves and concentrated distribution. However, as the rich mineral resources have been gradually depleted, the production of phosphate fertilizer in low-grade phosphate rock as the raw material is the development trend of the industry. Low-grade phosphate rock contains rare earth elements, rare earth is an important strategic resource, so the relevant provisions of the state mining of low-grade phosphate rock when the need for simultaneous extraction of rare earth elements, recovery of rare earth and phosphate from phosphate rock resources, the recovery of considerable value. Both the realization of the sustainable development of resources, but also bring benefits to society. Due to the current lack of rare earth phosphate rock phosphate industrial application technology, thus limiting the type of ore mining.
