本刊记者:我国中低品位磷矿占80%,资源丰而不富,中低品位磷矿的开发研究成为热点。作为这个领域的专家,请您谈谈中低品位磷矿直接利用的意义。石元亮:我国磷矿资源开发利用方式粗放,资源浪费严重,高品位磷矿资源锐减,近一年的时间里高品位磷矿石价格上升了一倍,已影响了我国磷化工的正常运行。由于磷矿资源的不可再生性及我国富磷矿储量的贫乏,充分利用中低品位磷矿已经成为实现磷肥工业可持续发展的必经之路。但是目前,我
Our correspondents: China’s low-grade phosphate rock accounted for 80% of rich and not rich in resources, low-grade phosphate rock research and development become a hot spot. As an expert in this field, please talk about the significance of direct use of low-grade phosphate rock. Shi Yuanliang: China’s extensive exploration and utilization of phosphate resources, serious waste of resources, sharp decline in high-grade phosphate rock resources, nearly a year’s high-grade phosphate rock prices have doubled, has affected the normal operation of China’s phosphorus chemical industry. Due to the irreplaceability of phosphate rock resources and the poor reserves of phosphate rock in our country, making full use of middle and low grade phosphate rock has become the only way to realize the sustainable development of phosphate fertilizer industry. But for now, me
