汞为稀少而重要的有色金属.全球汞资源量约为七十万吨,目前探明保有的储量约十七万吨.由于汞的稀少和有重要用途,因此有的国家称它为稀有金属或战略金属.长期以来,汞是我国重要的出口商品之一.随着汞矿的大量开采,我国汞资源逐年减少.鉴于矿产资源不可再生的特殊性和汞矿重要用途的不可替代性,对于我国的汞矿资源怎样才能做到合理开发、充分利用,既为当前着想,更有长远考虑,进行这样的研究与论证是很有必要的.
Mercury is a rare and important non-ferrous metal. The global mercury resource is about 700,000 tons, and the currently proven reserves are about 170,000 tons. Because of the scarcity of mercury and its important uses, some countries call it a rare metal. Or strategic metals. Mercury has long been one of China’s important export commodities. With the massive exploitation of mercury mines, China’s mercury resources have decreased year by year. Given the non-renewable nature of mineral resources and the irreplaceability of important uses of mercury mines, How can China’s mercury mineral resources be reasonably developed and fully utilized? Not only for the sake of the present but also for the long term, it is necessary to carry out such research and demonstration.
