作者全面而简要的介绍了当今的浮选情况,其中包括铜、铅、锌、铁等的硫化矿浮选。以赤铁矿与二氧化硅为例介绍了在氧化物浮选时利用电荷分选矿物的原理。盐水浮选即KCl与NaCl的分离,则是使用K离子和Na离子与捕收剂中的离子产生交换吸附的结果。塑料是当今人们生活中重要成份。对 The authors present a comprehensive and brief overview of today’s flotation conditions, including sulphide flotation of copper, lead, zinc and iron. Taking hematite and silica as an example, the principle of using electric charge to separate minerals during oxide flotation was introduced. Saltwater flotation, that is, the separation of KCl and NaCl, is the result of exchange-adsorption using K ions and Na ions with the ions in the collector. Plastic is an important ingredient in people’s lives today. Correct
