hello to all
im new to metal recovery business and im working about two months on small batches for gold recovery.
the method im using is Aqua regia and it works well for me.
i dissolve base metals in nitric acid and filter gold plated parts that seperates from board surface and after cleaning i dissolve gold in AR and after that the other processes will be done.
im intrested in copper and silver recovery too, I know about silver that i can percipitate silver in AgCl form when i add HCl in my nitric acid solution after gold filtering,
and for copper i know about adding sulfuric acid in hno3 solution for cuso4.5h2o percipitating. im intrested in CuSO4.5H2O pure form because im my country its more expensive than. pure copper form.
but i think these prosedures that i wrote is not that much easy that im thinking because of other base metald.
will you help me how to do this silver and copper separation and how to recover them?
best regards
