摘　　要：甘肃某尾矿为选铜尾渣,针对该尾矿性质特点,采用硫浮选-浮选尾矿脱泥-石英反浮选的工艺方案对其进行了综合回收,实验所得硫精矿可销售至硫酸厂,石英精矿可作冶炼造渣原料,实验尾矿可作烧制硅酸盐水泥的原料,实现了该尾矿资源的全综合利用。Aimed at the characteristics of the copper tailings in Gansu,the process of sulfur flotation-flotation tailings desliming-quartz reverse flotation is adopted for the comprehensive recovery.The sulfur concentrate obtained from the test can be sold to sulfuric acid plants,the quartz concentrate can be used as slagging raw materials for smelting,and the test tailings can also be used as raw materials for silicate cement,which realizes the full comprehensive utilization of this tailing resources.
