If you want to extract copper using dilute acid you must use sulphuric dilute acid. Pour it into a container and add some copper oxide (it's powder, I'm not sure if that's it's name) then take another container and put some filter paper on it and pour the mixture into that. It should look blue. Then add some filings into it and they should turn pink.
It should be a "pure" substance, but its really an alloy.
Copper is an element, not a molecule or a mixture. It is a pure substance made up of only copper atoms.
