摘　　要：金川神雾公司的铜渣转底炉直接还原-磨选生产线顺利投产,每处理1t铜渣将会产生0.5t左右的二次尾矿,需要进行综合利用。本文对铜渣二次尾矿的物理化学性质进行了分析,二次尾矿中主要是以透辉石和石英为主,其余为无形性相,且粒度较细-0.074mm91.70%。分析了铜渣二次尾矿的利用方式,包括生产胶凝材料、墙体材料、陶粒和用于农业生产的可行性。对一条年产30万m^3蒸压加气混凝土砌块生产线进行经济效果评价,项目总投资约为6,445.43万元,年消耗尾矿92,400t,年均净利润2,146.85万元,投资收益率41.04%,投资回收期3.07年,项目是可行的。The copper slag direct reduction-grinding production line in Jinchuan Shenwu Technology Co.,Ltd.is put into operation smoothly,for every ton of copper slag will produce about 0.5 t tailings,and it needs to be comprehensive utilization.The physical and chemical properties of tailing were analyzed in this paper,the crystalline phases in tailings were mainly by diopside and quartz,the rest is amorphous phase,and the proportion of-0.074 mm was 91.70%..The different utilization methods of tailings were analyzed,including the production of cementitious materials,wall materials,ceramsite and agriculture field.The economic effect is evaluated for the project of autoclaved aerated concrete block of annual output of 300,000 m^3.The total investment is about 64,454,300 yuan.And the annual consumption of tailings will be 92,400 tons.The annual profit will be 21,458,500 yuan,the investment return rate is 41.04%,and the investment recovery period is 3.07 years.The autoclaved aerated concrete block production project is feasible.
