摘 要: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。It is of practical significance for surveying and assessing tailings resources.According to the relation of the chosen mineral and the processing mineral and the tailings production,we established the principle of investigating tailings resources,and estimated that the copper tailings resources are about 1.5 billion tons and the content of copper is about 0.077%.At the same time,based on the thought of profit and loss balance,we constructed the economic model for analyzing tailings resources,and estimated that the economic grade is 0.07% for recycling single copper element if the copper price is not less than 35000 yuan per ton,and that makes it possible for making use of part of copper tailings resources at the present time.Resource structure determines the mode of its utilization.Based on the results of investigation and evaluation,it found that the main modes for copper tailings'comprehensive utilization include selecting again and used for mining filling or building materials in the future in China.According to the model,in order to further promote copper tailings resources development and utilization,it is not only necessary to release related information about tailings resource,but also necessary to work out a series of favorable policies,and then eliminate any restricted factor about making use of tailings resources.
