前言为了强化铜电解精炼过程,不少冶金工作者均从提高电流密度这一途径做了不少有益的研究和试验。在国内,有的厂在生产中采用常规直流电解已将电流密度提到360(安/米~2)左右,并获得了较好的效果和技术经济指标。在国外,运用周期反向电流电解法也将电流密度提高到410(安/米~2)(有 Preface In order to strengthen the process of electrolytic copper refining, many metallurgical workers have done a lot of useful research and experiments from the current density to improve this approach. In China, some factories use conventional DC electrolysis in production to refer to the current density of 360 (A / m ~ 2) or so, and obtain good results and technical and economic indicators. Abroad, the use of cycle reverse current electrolysis will also increase the current density to 410 (A / m ~ 2) (with
