我国是资源大国,同时又是资源贫乏的国家。但是现代化工业化城镇化国家的建设需要大量矿产资源的支撑。因此,我国不但需要进行优选富矿,同时要充分利用的贫矿,相对地扩大我国资源总量,还需要采用新工艺,提高工效,延长矿山的服务年限。
My country is a resource-rich country, and at the same time it is a resource-poor country. However, the construction of a modernized industrialized urbanized country needs the support of a large amount of mineral resources. Therefore, our country not only needs to carry out the optimization of rich ore, but also make full use of the lean mines, and relatively expand the total amount of resources in our country. We also need to adopt new techniques to improve work efficiency and extend the service life of mines.
