本文对某含银多金属铅锌硫化矿中自然银在浮选中对各种捕收剂、调整剂作用效果进行了探讨,捕收剂以丁胺黑药和磷胺—4号混合用药优于下基黄药.调整剂以硫代硫酸钠和硫酸锌混合使用能较好地抑制锌、硫,而对铅有弱抑制作用,但对银影响不大.石灰是黄铁矿有效抑制剂,但对自然银也有抑制作用,所以往往多金属铅锌硫化矿的最佳浮选条件,不一定是银矿物的适宜浮选条件.并论述了对提高银回收率的看法.
In this paper, a silver-bearing polymetallic lead-zinc sulfide ore natural silver in the flotation of various collectors, the role of regulator effect were discussed, the collector to butylamine black and phosphorus amine-4 mixed medication excellent In the next base of xanthophyll.Adjusting agent with sodium thiosulfate and zinc sulfate mixed can better inhibit zinc, sulfur, but has a weak inhibitory effect on lead, but has little effect on silver.Limestone is a potent inhibitor of pyrite , But also has an inhibitory effect on natural silver. Therefore, the optimal flotation conditions of the polymetallic lead-zinc sulfide ore are not necessarily the suitable flotation conditions for silver minerals, and the opinions on improving the silver recovery rate are discussed.
