塞洛维德(Cerro Verde)于1977年4月投产。原电积车间设计能力为年产阴极铜33 000 t,采用184 A/m2的电流密度,电流效率为84.5%。1994年该矿山并着手进行扩产,以增加产能至年产阴极铜48 000 t,采用250 A/m2的电流密度,电流效率为90%。到1997年,通过工艺的革新优化,并提高电流密度,使阴极铜的产量超过了该设计能力。2002年继续通过提高电流密度增加产量,电流密度达到370 A/m2。本文围绕着如何通过改进电解液的流量、成分和温度、电极几何尺寸、电解槽、添加剂、电解周期及操作实践以实现在提高阴极铜质量的同时达到较高生产能力进行讨论。
Cerro Verde was put into operation in April 1977. The original design capacity of the shop for the annual output of cathode copper 33 000 t, the current density of 184 A / m2, the current efficiency of 84.5%. In 1994, the mine commenced its expansion to increase its production capacity to 48,000 t / a of cathode copper. The current density was 250 A / m2 and the current efficiency was 90%. By 1997, through the process of innovation and optimization, and increase the current density, so that the cathode copper production exceeded the design capacity. In 2002, the current density continued to be increased to 370 A / m2 by increasing the current density and increasing the output. This article focuses on how to achieve higher productivity while improving cathode copper quality by improving electrolyte flow, composition and temperature, electrode geometry, electrolyzer, additives, electrolysis cycles and operating practices.
