摘　　要：以某铜尾矿的资源化利用为目标,确定了合理的工艺流程及参数,用浮选工艺从铜矿尾矿中进一步回收铜金属,铜精矿的品位为15.83%,回收率为72.61%,提高了资源利用率。再以煤矸石为配料生产建筑烧结砖,对影响产品质量指标的配料比、烧成温度、保温时间等因素分别了进行研究,确定最佳工艺条件为铜尾矿与煤矸石配料比7∶3,烧成温度950℃,保温时间1.5 h。产品强度达到GB5101—2003中MU20级质量标准。With the purpose of comprehensive utilization of copper tailings,a reasonable process and some parameters are determined to further get copper concentrate from copper tailings by flotation process.The grade of the copper concentrate reaches up to 15.83%,and the recovery to 72.61%,improving the utilization efficiency of resources.Then the copper tailings are used as the main raw material and the gangue as cementing agent to produce fired bricks for buildings.And some researches on the mixture ratio,sintering temperature and holding time are carried out.Then the optimum conditions are determined as the ratio of the copper tailings and gangue 7∶3,the sintering temperature 950 ℃,and the holding time 1.5 h.The strength of the product can reach the MU20-class of the GB5101-2003 quality standards.
