尽管我国化工原料矿产中的磷矿资源丰富 ,但适合大规模开采的矿少 ,矿石品位低 ,而适合生产高浓度磷复合肥的优质磷矿较为短缺 ;我国的硫资源主要是易造成环境污染的硫铁矿 ,由于制酸成本高 ,再加上污染环境 ,在国际上已趋于被淘汰的地位 ,目前已开始使用自然硫资源 ;钾盐资源
Although China is rich in phosphate rock in chemical raw materials and minerals, it is suitable for large-scale mining with few ore grade and low quality ore grade, while high-quality phosphate rock suitable for producing high-concentration phosphorus compound fertilizer is in short supply. Our country’s sulfur resources are mainly likely to cause environmental pollution Of the pyrite, due to the high cost of acid production, coupled with pollution of the environment, has been in the international arena has been eliminated, has now begun to use natural sulfur resources; potash resources
