(一)概 述 在1989—1990年间,估计印度国内每年所需磷矿量可能会超过400万吨。但它的磷矿储量却不多,全国推算的远景储量约1.5亿吨,初探储量1.2亿吨,其中仅有可采储量2500万吨。1969年以前所需磷矿几乎全部靠进口,后来在乌代普尔(udaipur)的拉贾斯坦(Rajasthan)找到了Jhamar Kotra (I) Overview During 1989-1990, it is estimated that more than 4 million tons of phosphate rock will be required annually in India. However, its reserves of phosphate rock are few, the country’s projected long-term reserves of about 150 million tons, initial exploration reserves of 120 million tons, of which only recoverable reserves of 25 million tons. Most of the phosphate rock required before 1969 was imported, and Jhamar Kotra was later found in Rajasthan, Udaipur
