the first reaction doen't work.you can dissolve copper in nitric acid,then add NaOH to produce CuO,dissolve in sulfuric acid,and react with
hydrazine.and you can also get pure copper from the electrolysis of copper chlorine solution.
aluminum is not a good reducer,because aluminum is always oxidized,and the aluminum oxide is impurities,that's annoying
