按现行磷矿产品质量标准,占我国磷矿储量90％以上的矿石都需要选矿富集。而在我国磷矿资源中,90％以上属于海相沉积磷块岩,俗称胶磷矿。此类磷矿的碳酸盐含量高,且脉石矿物常以微细颗粒分散嵌布于磷矿物之中,如何分选一直是近三十年来世界瞩目的研究课题。这说明磷矿选矿技术的进步对于推动我国磷肥工业的发展具有特别重要的意义。 According to the current quality standards of phosphate rock products, accounting for more than 90% of China’s phosphate rock reserves require ore enrichment. In our phosphate rock resources, more than 90% belong to the marine sedimentary phosphorite, commonly known as phosite. Such phosphate rock is high in carbonate content, and gangue minerals are frequently dispersed and embedded in phosphorous minerals with fine particles. How to sort them has been the subject of world attention for nearly thirty years. This shows that the progress of phosphate rock beneficiation technology for promoting the development of China’s phosphate fertilizer industry has a special significance.
