Problems with lead anodes in copper electrolysis
Thread Content
During the copper electrolysis process, since the lifespan of lead anode plates is generally 3–4 years, they tend to deform over time as they gradually peel away and thin out, which leads to an increase in short circuits and more anode sludge. Are there any effective methods to keep the anode plates flat? And how often should the anode sludge accumulated in the electrolyzer be removed?
Reply 1# Is the table electroformed copper? The copper deposited at the anode during electrolysis should be rough copper, right? The cathode is basically stainless steel, right?
I want to know too. Going back to floor 2, the original poster was talking about lead anodes used for purification and filtration
Reply to 3# 912love930: Could you explain the purification and filtering process in more detail? Thank you
Reply to 2# Caiyun Yisan: The cathode is a permanent 316 cathode, while the anode is made of lead plate
I don’t know whether lead plates are used in electrolyzers or for copper removal. .
Can everyone distinguish between electrolysis, electrowinning, and copper removal? Personally, I think the difference between them is quite large. Many times, we are not on the same page. I wonder if anyone agrees?
Reply to 1# Table: During this process, you can add some cobalt sulfate, at around 100-150PPM, which will protect your lead plates and allow the lead anodes to last for 6 to 8 years. Cobalt sulfate can form a sticky composite with the lead oxide that forms on the surface; this composite adheres to the anode and prevents the inner layer of lead from oxidizing and flaking off. If you decide to produce it yourself, you can give it a try. As for cleaning the anode sludge, it depends on your own design choices, as these factors affect the production process: 1) The total flow rate and velocity of the liquid, 2) The depth of the electrowinning tank, 3) The efficiency of the system for purifying the anode solution. These factors determine the frequency at which the anode sludge needs to be cleaned; with a well-designed system, this can be done every 8 to 12 months
When the service life of lead anode plates comes to an end, they can be sold at a reduced price to the manufacturer, who will then melt them down and cast them again; all manufacturing companies offer this service； The service life of lead anode plates generally does not exceed 5 years. As is well known, lead is slightly soluble in acid; therefore, I believe this problem cannot be solved for the time being until new materials become available. As for the lead anode sludge in the tank, it is best to clean it once every six months; of course, you can also decide whether to clean the tank promptly based on the lead content in the cathode copper.
Dude, how are your lead anodes designed? With a stainless steel cathode, how are the anode and cathode lifted out? Can a lifting device be used? ?
