Is there any way to recover the electroplated copper layer from a stainless steel substrate (the copper layer accounts for 15% of the weight)? Those who know of viable methods can add me as a friend so that we can discuss potential cooperation
Recycling copper on a stainless steel substrate? Or recycle the copper on the stainless steel substrate?
It is estimated that extraction should work. First, the copper needs to be removed; acid washing is probably the only method for this. However, when using acid washing, some of the iron will also be corroded and removed as well. It’s a bit difficult to separate copper from iron when they are together. Based on my experience, weak-acid cation resins can separate iron from copper. However, the copper content in your sample seems to be quite high; I’m not sure what concentration of copper ions is present in the pickling solution. If the concentration is above 5%, it’s likely that iron will not adsorb to the resin easily. Extraction is the only option to consider. As for the specific extractant, one should consult professionals.
First, carry out pickling, then replace the copper in the acid.
{:3_68:} Copper is relatively soft; perhaps it’s possible to roughly separate it physically from the iron base, then purify the copper through electrolysis, or use acid to remove the iron
