Flotation of Xinhua molybdenite using sodium sulfide as modifier YIN Wan-zhong(印万忠)1, ZHANG Li-rong(张丽荣)1, Xie Feng2 1. School of Resource and Civil Engineering, Northeastern...: The feasibility of using sodium sulfide as the sole modifier for the flotation of Xinhua molybdenite ore was examined. The potential mechanisms involved in the different flotation systems were discussed......
in recent years [2]. Of all the land nickel reserves, 30% exists as sulfide ores with the balance comprised of oxide ores. The oxide ores are typically referred to as nickel laterite ores [3]. In traditional nickel industries, about 60% of the metal nickel was produced from sulfide ores about ten years ago [4]. However, miners of nickel sulfide ores have been confronted with increasing challenges......
