description The invention belongs to the technical field of mineral processing, and particularly discloses a flotation method of residual slope product type lead-zinc sulfide ore, which comprises the following steps: adding sodium sulfide and a collecting agent into the raw ore of the residual slope product type lead-zinc sulfide ore for ore grinding; and zinc sulfate, sodium sulfite and a collecting agent are added into an ore grinding product for one-time roughing, two-time scavenging and three-time concentration, middlings are sequentially returned, and lead concentrate and lead tailings are obtained through flotation. According to the flotation method for the residual slope product type lead-zinc sulfide ore, good recovery of lead can be achieved, and meanwhile comprehensive recovery of gold and silver is achieved. 本发明属于矿物加工处理技术领域,具体公开了一种残坡积型硫化铅锌矿的浮选方法,所述浮选方法在残坡积型硫化铅锌矿原矿中添加硫化钠和捕收剂进行磨矿,磨矿产品再添加硫酸锌和亚硫酸钠以及捕收剂进行一次粗选、两次扫选和三次精选,中矿顺序返回,浮选获得铅精矿和铅尾矿。本发明提供的残坡积型硫化铅锌矿的浮选方法,可实现铅的良好回收,并同时实现金银的综合回收。
