据国家综合部门论证,本世纪初,我国主要化工矿物原料形势依然严峻,其中,2000年缺口为:硫铁矿200～400万吨,磷矿710～930万吨,钾肥425万吨,硼矿100万吨;到2010年缺口为:硫铁矿900～1100万吨,磷矿1720～1950万吨,钾肥525万吨,硼矿180万吨。从我国化工矿产资源形势条件分析,我国固体钾盐资源严重短缺,近期找矿难
According to the national comprehensive department, at the beginning of this century, the situation of major chemical mineral raw materials in China is still grim. Among them, the gap in 2000 was: 200-400 million tons of pyrite, 710-930 tons of phosphate ore, 4.25 million tons of potash, and boron 1 million tons; By 2010, the gap will be: 900 to 11 million tons of pyrite, 1720 to 19.5 million tons of phosphate rock, 5.25 million tons of potash, and 1.8 million tons of boron. From the analysis of the situation of China’s chemical mineral resources, there is a serious shortage of solid potassium resources in China and it is difficult to find ore in the near future.
