ABSTRACT Coal preparation plants are increasingly turning to alternative sources of water to reduce their consumption of fresh water. These alternative sources can vary significantly in ionic content. This review discusses the effect of dissolved inorganic electrolytes on coal flotation. It is argued that increasing process monitoring will enable a better understanding of the effects of salts on the flotation process. A pragmatic approach in monitoring is essential to differentiate significant factors from insignificant ones controlling the performance of coal flotation units in salt water. The effects of inorganic electrolytes on the air–water interface and the solid–liquid interface are reviewed to assist in the interpretation of industrial results.

盐水中的煤浮选：电解质对界面和工业实践的影响

摘要 选煤厂越来越多地转向替代水源，以减少对淡水的消耗。这些替代来源的离子含量可能会有很大差异。本综述讨论了溶解无机电解质对煤浮选的影响。有人认为，增加过程监控将有助于更好地了解盐对浮选过程的影响。实用的监测方法对于区分控制盐水中煤浮选装置性能的重要因素和不重要的因素至关重要。综述了无机电解质对空气-水界面和固-液界面的影响，以帮助解释工业结果。
