中国磷矿储量约为130亿t,虽然从储量规模上看较为乐观,但高品位的磷矿石仅占磷矿资源的20%左右,贫矿所占比重较大。这种资源结构现状要求在使用磷资源时,要做到物有所值,物尽其用。实现磷资源的合理利用,应当从源头上的采富弃贫着手。据专家介绍,每开采1t磷矿石,就要丢弃7～8t
China’s phosphate rock reserves are about 13 billion tons. Although optimistic about the scale of reserves, high-grade phosphate rock accounts for only about 20% of the phosphate rock resources, with a large proportion of poor ore. The current status of resource structure requires the use of phosphorus resources, we must achieve value for money, make the best use. To achieve the rational use of phosphorus resources, we should abandon the poor from the source. According to experts, every mining 1t phosphate rock, we must discard 7 ~ 8t
