本文系统地介绍了浮选研究中常用的电化学研究方法及其基本概念。选择地介绍了世界学者用电化学法研究黄铁矿、方铅矿、辉铜矿和黄铜矿等矿物的代表性结论,侧重于矿物浮选的电位范围、疏水实体以及近年的研究结论。作者在自己对毒砂可浮性研究中,运用电位-PH图对毒砂浮游问题作了扼要的分析。 This article systematically introduces the commonly used electrochemical research methods and their basic concepts in flotation studies. The representative conclusions of electrochemistry study on the minerals such as pyrite, galena, chalcopyrite and chalcopyrite from world scholars are introduced selectively. The potential range of mineral flotation, hydrophobic entities and recent research conclusions are also introduced. In his study of arsenopyrite floatability, the author made a brief analysis of the problem of arsenopyrite flooding using the potential-PH diagram.
