Copper removal in the second stage of liquid purification process
Thread Content
We are using stainless steel plates for the second-stage copper removal process; what is the reason why the resulting copper plates are difficult to separate? After long-term use of the plate, the black copper sludge that forms on it is difficult to remove? Has anyone used a residual anode as the cathode? How is electrical connection controlled?
Difficulty in peeling is mostly caused by chloride ions corroding the cathode. If the black copper produced by copper removal is sent back to the furnace for processing, the residual electrode can be tried out as a cathode.
Even electricity? Does it refer to a short circuit or connecting a circuit?
It seems that when copper is electrowonded using stainless steel plates, this problem arises after some time of use. It must be corroded; the stainless steel plate needs to be treated regularly. What does \"lian dian\" mean?
Yes, I’m most afraid of chloride ions~~~
For copper removal, especially in the latter stages when the concentration of copper ions is low and black copper is produced, residual electrodes are generally used
