电积和电解精炼中操作实践与延长不锈钢阴极寿命的关系

The link between operational practice and maximizing the life of stainless steel electrodes in electrowinning and electrorefining applications

长期已来已证明采用不锈钢阴极板电积和电解精炼生产阴极铜是一种可靠技术。芒特·艾萨矿业有限公司是这一技术的原创者。经验表明,这些阴极在电解精炼中寿命可超过十五年,在电积精炼中可达十年。生产系统的正确管理以及对细节的关注将确保电极在这两种应用中的寿命。电解液的氯化物含量、电流密度、剥离方式、电流分布、出铜方式以及阴极电解周期都会影响阴极板寿命。本论文旨在讨论阴极管理中遇到的共同问题,特别强调了电积精炼厂遇到的问题。这些建议主要是根据艾萨电解小组进行的试验工作,以及通过与客户合作获得的经验和知识基础上得出的。

The use of a permanent stainless steel cathode plate in both electrowinning and electrorefining applications has long been accepted as a proven technology for cathode copper production. Correct management of the operating system and attention to detail will ensure the life of the electrode in both application. Chloride levels in electrolyte current density, the use of shorting frames, current distribution, harvesting patterns, and cathode-plating cycles all affect cathode plate life.
