开展尾矿资源调查评价具有重要的现实意义。借助入选矿石量及精矿与尾矿产出量之间的关系,确定了尾矿资源调查方法,并测算得全国铜矿尾矿资源总量大致为15×108t,铜平均品位约为0.077%;同时,基于盈亏平衡的思想,构建了尾矿资源经济评价模型,并且测算确定,在铜价不低于35 000元/t的条件下,回收单一铜元素的经济品位为0.07%。资源结构决定其利用模式。根据调查评价结果判断,未来我国铜矿尾矿资源利用的主要模式是尾矿回选及尾矿用于采矿充填或用作建筑材料两个方面。根据尾矿资源利用模式,要进一步推动尾矿资源开发利用,不仅需要及时发布尾矿资源数据信息,而且更需要落实相关激励政策,努力消除尾矿资源开发利用的限制性因素。
Carrying out tailings resource investigation and evaluation has important practical significance. Based on the relationship between the amount of ore selected and the output of tailings, the tailings resources survey method was determined and the total amount of tailings resources in the country was estimated to be about 15 × 108t with average copper content of about 0.077%. At the same time, based on the idea of breakeven, an economic evaluation model of tailings resource was constructed and the economic grade of recovery of single copper was 0.07% when the copper price was not less than 35 000 yuan / t. Resource structure determines the pattern of its use. According to the investigation and evaluation results to determine the future of China’s copper mine tailings utilization of the main pattern of tailings and tailings for tailings for mining filling or used as building materials in two areas. According to the tailings resource utilization pattern, to further promote the development and utilization of tailings resources, it not only needs timely release of tailings resource data information, but also need to implement the relevant incentive policies and strive to eliminate the restrictive factors of tailings resource development and utilization.
