| 摘 要： | 硫化钠是一种重要的浮选调整剂, 在浮选中具有广泛的应用.在处理有色金属硫化矿时，硫化钠可作为抑制剂、脱药剂、活化剂；在处理有色金属氧化矿时，硫化钠则是重要的硫化剂.在浮选溶液电化学中，硫化钠既可以调节矿浆pH，也可以调节矿浆电位Eh.本文将硫化钠在实际中的应用与其基本性质相结合，论述硫化钠在浮选中的不同作用及机理，指出控制硫化钠的用量和作用时间是合理使用硫化钠的关键.

| Abstract: | Sodium sulfide is an important regulator with a wide range of application in the flotation. It can act as depressant, reagent removal agent and activator in processing non-ferrous metal sulfide, while as important vulcanizing agent in non -ferrous metal oxide ores. In the electrochemistry of flotation solution, it can adjust the pH and Eh of slurry. By combining practical application with basic properties of sodium sulfide, this paper discusses its different functions and mechanisms in flotation, and points out that the key to its reasonable use is to control its dosage and action period. |
