浮选矿浆中的离子成分,(特别是循环用水,其离子浓度积累很高的时候)对优先浮选有很大影响。诺里尔斯克选矿厂改为循环用水,循环水的离子成分的调整问题便成为铜-镍矿石优先浮选的重要工艺因素。矿石中的主要金属矿物有黄铜矿、方黄铜矿、镍黄铁矿和磁黄铁矿,按直接优先浮选流程进行浮选,依次获得铜、镍和磁黄铁矿精矿。用丁基黑药作铜矿物捕收剂,CφK为起泡剂。镍浮选用丁基黄药作捕收剂,
The ionic components in the flotation slurry, especially in recycle water, when the ion concentration is highly accumulated, have a great influence on the preferential flotation. Norilsk concentrator into recycled water, recycled water ion composition adjustment issues have become the copper-nickel ore preferential flotation of the important process factors. The main metallic minerals in the ore are chalcopyrite, chalcopyrite, pentlandite and pyrrhotite. Flotation is carried out according to a direct preferential flotation process, and copper, nickel and pyrrhotite concentrates are sequentially obtained.
