Hi all

How to purify copper alloys electrochemically ? please describe all possible commerically feseable ways and also pls specify any commerical set ups /resource that can do the above process

Hello,

I have no knowledge about commercial aspects of electrochemical purification, but I'd say that if you can produce a redox couple on copper, then you can oxidize the other metal and purify it; but the term "pickling" is frequently used for the thing you're asking for, I think.

Pickling is basicly an acidic treatment, but the acid must be of a non-oxidizing one in order not to corrode copper; the other metal(s) in the alloy will eventually be solubilized and leave copper by going into the solution, and copper will remain intact. This may be a good measure.

If the impurities are organic-based, acidic treatment after heating the copper part beyond 500°C will be more helpful.

These are pure-chemical ways to treat an impure copper alloy, but wait for other friends' posts.

Electrochemical purification is a process used to remove impurities from copper alloys through the use of electricity. This method is widely used in the industry as it is efficient, cost-effective, and environmentally friendly.

One commercially feasible way to purify copper alloys electrochemically is through electrolysis. This involves passing an electric current through a solution containing the copper alloy, causing the impurities to be attracted to the anode and the pure copper to be deposited on the cathode.

Another method is called electro-winning, which involves using an electric current to extract the copper from a solution containing the alloy. This process is commonly used in large-scale commercial operations.

There are also specialized electrochemical purification systems and equipment available on the market. These include electrowinning cells, which use a series of anodes and cathodes to purify the copper, and electrolytic cells, which use a single anode and cathode to purify the alloy.

Some commercial set-ups and resources that can perform electrochemical purification include large-scale mining and processing companies, specialized purification facilities, and equipment manufacturers. It is important to research and consult with experts in the field to determine the best and most cost-effective method for your specific alloy and production needs.

In conclusion, electrochemical purification is a highly effective and widely used method for purifying copper alloys. It offers numerous benefits and there are various commercially feasible ways to implement this process, depending on the specific requirements and resources available.
