Float Metals One-by-One Selectively: Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe: pH 6-6.5 is where Pb/Zn/Fe are least hydrophobic while Cu is most hydrophobic. Great pH to Recover Cu. pH 7.5-8 is where Zn/Fe are least …

We can summarize this by saying that Zn is a stronger reducing agent than Cu. Part I: The stockroom of the virtual lab contains solutions of Cut2, Mg+2, Zn+2, and Pb+2 ions, and the correspond metals (Cu, Mg, Zn, and Pb). Your first task is to order Cu, Mg, Zn and Pb from strongest to weakest reducing agent.
