摘　　要：冬瓜山矿石属复杂的高硫铜矿石,高碱铜硫分离工艺给选硫作业带来很大困难,探索合适的选硫工艺具有十分重要的意义。通过对活化剂种类、工艺流程研究,采用磁选-浮选选硫流程,磁选尾矿使用水力旋流器浓缩,取得了理想的生产指标。The refractory copper-sulper ore in Dong Gua Shan copper ore and in higher alkaline medium to carry out copper-sulfur separation,so it is very difficult to recovery the pyrite,to search reasonable processing technology is very important.Through research of the activator kind and processing,to adopt magnetic separation-flotation processing,concentration the tailings of magnetic separation by hydrocyclones,the result is excellent in production practice.
