一、当前存在的主要问题我国的矿产资源总量丰富,在世界上无疑是矿产资源大国,但按人均占有量统计,仅在世界上排名第80位。当前,我国矿山的回采率和矿产综合回收利用率仍然较低。据558个国营矿山(井)统计,回采率低于部颁标准的占48％;主要有色金属矿产采、选、冶回收率平均约为55％,非金属矿产的采、选加工回收率大多低于60％;冶金、化工、建材部门相当多的矿山回采率也低于设计要求。

I. Main Existing Problems China is rich in total mineral resources and undoubtedly the largest mineral resource in the world. However, according to the statistics of per capita possession, it ranks only 80th in the world. At present, China’s mining recovery rate and recovery rate of comprehensive utilization of minerals is still low. According to the statistics of 558 state-owned mines (wells), the recovery rate is 48% lower than that of the ministerial standards. The average recovery rate of mining, dressing and smelting of major non-ferrous metals is about 55%. The recovery rate of mining and processing of non-metallic minerals is mostly Less than 60%; metallurgical, chemical, building materials sector quite a number of mining recovery rate is lower than the design requirements.
