据报导，到２０００年底，我国共探明磷矿储量１３１亿t；其中基础储量为３８亿多t；而磷矿平均品位仅为１６．９％，P２O５大于３０％的富矿只有１０．７亿t，绝大部分是难以精选富集的中低品位矿石，可利用矿区保有的可采和可预采储量为２１亿t，折标矿约１４亿t；如果按目前
It is reported that by the end of 2000, a total of 13.1 billion tons of phosphate rock reserves had been discovered in our country, of which the basic reserves were over 3.8 billion tons. The average grade of phosphate rock was only 16.9% and that of rich ore with P2O5> 30% was only 1.07 billion t, the vast majority is difficult to enrich enrichment of low-grade ore, available mining reserves and recoverable recoverable reserve of 2.1 billion t, about 1.4 billion t mark mine; if the current
