%X 氰化尾渣多元素浮选是较为可靠的、效率高的回收金属的方法，充分利用氰根对铜矿物的抑制作用，进行铜、铅、锌浮选分离。但受到环保要求和使用成本的限制，在氰化浸出过程中，尽量降低氰化物的含量，由此造成多元素浮选效果发生变化。为了便于生产控制，查找最佳控制条件，实验得出浮选过程中氰根含量在2500 mg/L时，铜锌分离较好。在氰化物不足时，添加90 g/t绿色环保药剂巯基乙酸钠，即可满足技术需求。<br />
Multi-element flotation of cyanide tailings is a reliable and efficient method for metal recovery, which makes full use of the inhibitory effect of cyanide on copper minerals to separate copper, lead and zinc flotation. However, due to environmental protection requirements and limited by the cost of use, the cyanide content is reduced as much as possible in the cyanide leaching process, resulting in a change in the multi-element flotation effect. In order to facilitate production control and find the best control conditions, the experimental results show that when the cyanide content is 2500 mg/L during the flotation process, the copper-zinc separation is better. When cyanide is insufficient, add 90 g/t green environmental protection agent sodium mercaptoacetate to meet the technical requirements.
