【摘要】：近十年国民经济快速发展,矿山技术工艺和装备水平极大提高,推动了我国矿产节约和综合利用水平提高。主要表现为:一是采选水平稳步提高,开采回采率和选矿回收率总体处于较高水平;二是尾矿的矿山固废堆存量大,利用潜力巨大;三是近年我国废旧金属回收发展较快,积存的大量废旧产品已经进入回收再利用的窗口期,有望减少对原矿资源的消耗。2012年以来,受国内外经济增速放缓影响,主要矿产品价格持续大幅下跌,矿山综合利用产值大幅回落。当前亟需开展全国范围矿产资源综合利用调查评价,推广先进技术,建立综合利用税收优惠制度,引导矿山企业自觉节约利用各种资源,进一步优化矿山"三率",提高尾矿利用、废旧金属的资源化水平,从而推动全国矿产资源节约与综合利用水平的提高。
[Abstract]:With the rapid development of the national economy in the past ten years, the level of mining technology and equipment has been greatly improved, which has promoted the level of saving and comprehensive utilization of mineral resources in China. The main results are as follows: first, the level of mining and dressing has been steadily improved, the recovery rate and recovery rate of ore dressing are generally at a higher level; the second is the large quantity of solid waste heap of tailings, and the great potential for utilization; the third is the rapid development of the recovery of waste metals in China in recent years. A large number of waste and used products accumulated have entered the window period of recycling and reuse, which is expected to reduce the consumption of raw ore resources. Since 2012, the prices of major mineral products have continued to drop sharply because of the slowdown in economic growth both at home and abroad. The output value of comprehensive utilization of mines dropped sharply. At present, it is urgent to carry out the investigation and evaluation of comprehensive utilization of mineral resources nationwide, to promote advanced technology, to establish a preferential system for comprehensive utilization of taxes, and to guide mining enterprises to consciously economize and utilize all kinds of resources. Further optimize the "three rates" of mine, improve the utilization of tailings and the level of recycling of waste metals, thus promoting the level of saving and comprehensive utilization of mineral resources in China.
