Separating Copper from Gold (electroplating)
2022-5-1 It will build up and must be removed from the solution. The USBM published work on the EW of Au, Ag Cu using square wave pulse of 2.5 V for 10%-30% of a period of 100 to 1000 milliseconds. The remaining time was 0 V. This resulted in plating of gold and silver and minimal plating of Cu. But the Cu needs to be removed from the circuit.

PARTING: Separate Gold and Silver by Melting
2016-11-3 The gold is washed thoroughly and sweetened in wooden filters, boiling distilled water being poured through it until the washings will no longer redden blue litmus paper. The silver is precipitated from these washings as chloride by the addition of salt. The gold is then pressed, dried, melted, and cast into bars, which are from 998 to 999 fine.
