针对云南永平水泄瓦场氧化铜矿嵌布粒度细,氧化程度高,精矿产品质量差的问题,对该矿采用浮选法进行选别。由于该矿石属于混合型,在浮选选别上进行了不同方案的比较,最终拟定先对硫化铜矿和氧化铜矿进行混合浮选,然后用硫化钠对氧化铜矿进行多次硫化多次捕收的选别方案,采用该方案选矿获得了良好的铜精矿指标。
Aiming at the problems of small grain size, high degree of oxidation and poor product quality of copper oxide ores in Yongping, Yunnan Province, the method of flotation was adopted for the mine. As the ore is a mixed type, flotation sorting on the different programs were compared, the final plan for the first copper sulfide ore and copper oxide flotation, and then with sodium sulfide copper sulfide multiple times Catching the selection program, using the program beneficiation obtained good copper concentrate indicators.
