在铜电解精炼生产中,近几年来,流传着一种看法:高电流密度就代表高水平。至今还有人认为,提高电流密度,对于充分挖掘现有电解生产技术设备的潜力,迅速提高老企业的产量,仍不失为一种经济的有效途径。也有人研究、分析铜电解过程中阳极钝化的主要原因之后,认为电流密度提高到400(安/米~2),不但在技术上是可能的,经济上 In copper electrolytic refining production, in recent years, there is a common belief that high current density represents a high level. Some people still think that increasing the current density is still an economically effective way to fully tap the potential of the existing electrolytic production technology and equipment and rapidly increase the output of the old enterprises. Some people also studied and analyzed the main reason of anodic passivation in copper electrolysis process. It is considered that increasing the current density to 400 (A / m ~ 2) is not only technically possible but also economically
