高电流密度铜电解工业化试验研究

Experimental Study on Industrialization of High Current Density Copper Electrolysis

阐述了高电流密度铜电解工业化试验情况。以现有铜电解工业生产槽为试验槽,通过减少阴阳极数数量将电流密度提高至335 A/m 2,在其他生产工艺条件不变前提下,通过采用了不同重量的阳极板、不同流量的电解液循环量,考察电流密度为335 A/m 2条件下,阳极板重量、电解液循环量对槽压、阴极铜表面结晶状态、电解液温度均匀性、电解液成分分布及浓差极化的影响,为下一步金冠铜业铜电解生产提高电流密度提供技术支持。

The industrial test of high current density copper electrolysis was described.The current density was increased to 335 A/m 2 by reducing the number of anode and cathode.The effects of anode plate weight and electrolyte circulation on cell pressure and cathode copper surface crystallinity were investigated under the condition of current density of 335 A/m 2.The results provided technical support for the improvement of current density in the next step of copper electrolysis production of Jinguan copper.
