Electrorefining/electrowinning gold

++++++

We want to strip gold from electronic circuit boards in a cyanide bath (12g/L) and ,in turn, plate the gold onto a stainless steel wool cathode while suppressing any copper that may have been stripped during the process. We are using a platinum clad anode. What is the recommended voltage and time needed. What is the physical appearance of the cathode while and after the plating process.
