Cementation: they would take the liquid left over from floatation and put it in a tank with iron scrap metal and some reagent (acid?). The iron releases the Cu from its compounds, replaces it and I believe the free Cu plates the surface of the scrap. It somehow builds up and can be shipped in much purer state.
