Can treating copper-iron slag with dilute sulfuric acid increase its copper content?

If dilute sulfuric acid is used to treat the iron residues, will the copper content increase as a result? I would appreciate some guidance from those with more experience on how to proceed. What I mean is to treat these iron residues in such a way as to increase the copper content in the resulting residues
Due to its large specific surface area, most of the copper in iron slag may already have been oxidized to CuO; CuO can also be dissolved if treated with dilute sulfuric acid. So the experimental results may not be very satisfactory.
I didn’t understand what the original poster meant; please explain the question more clearly. In the phase, are copper and iron elements or compounds? Is your goal to extract copper metal or to conduct analysis?
As long as all the slag is dissolved, there will be no impact; after all, the proportion of the substance you are using in the slag should remain constant. Copper in iron slag exists in the form of oxides, so it will dissolve completely in sulfuric acid solution. Therefore, the copper content should not be affected. I’m not sure if this is what the original poster meant
