塞洛维德(国外英文资料) Serao Wade (Cerro Verde) was put into operation in April 1977. The design capacity of primary electrodeposition workshop is annual cathode copper 33000 T, adopting current density of 184 A/m2, current efficiency is 84.5%. In 1994, the mine was expanded to increase production capacity to an annual output of 48000 t of cathode copper, with a current density of 250 A/m2 and a current efficiency of 90%. By 1997, through the process of innovation, optimization, and increase the current density, so that the cathode copper production exceeded the design capacity. In 2002, the current density was increased by increasing the current density, and the current density reached 370 A/m2. This paper focuses on how to improve the quality of cathode copper in order to realize and achieve higher production capacity to discuss many classmates introduced their electrolyzer current density by improving the electrolyte composition and temperature, flow rate, electrode size, electrolyzer, electrolytic additives, cycle and operation practice, also introduced their own DC power consumption. Here, I would like to ask you, the operation of the electrolyzer current density and trough pressure is proportional to the relationship? Many teachers said that the higher the current density, the higher the DC power consumption, and if so, the current density of the electrolyzer is not directly proportional to the tank pressure Personally, I think that the current density in the electrolyzer is not directly proportional to the tank pressure Because with the increase of the current density, the polarization of the electrode is the constant irreversible growth of the overpotential, and more importantly, the polarization of the solution. The extent of this polarization is more and more serious as the current density increases, and it can not be increased with the current density at a certain ratio. Because of the different manufacturing techniques of various electrolytic cells, the same curre
