摘　　要：在缓冷渣选铜中加入石灰调浆,可有效地提高矿浆的粘性和气泡的韧性,延缓了矿物颗粒的沉降速度,增加了矿物颗粒与上升气泡的接触机会,降低了泡沫的兼并速度,改变了靠大剂量使用Z200和丁基黄药才能维持的矿浆粘度和气泡韧性的状态。可大幅度降低Z200和丁基黄药的药剂单耗,每年可节约药剂成本166万多元。Adding lime slurry to the slow cooling slag for separation copper can effectively improve the viscidity of slurry and the toughness of bubbles.The sedimentation rate of mineral particles is delayed,which can increase the chance of contact between mineral particles and rising bubbles.The merging speed of the foam is reduced,which changes the slurry viscosity and bubble toughness that can be maintained by using large doses of Z200 and butyl xanthate.It can greatly reduce the single drug consumption of Z200 and butyl xanthate,and save more than 1.66 million yuan of drug cost every year.
