method to separate gold and copper

Separating Copper from Gold (electroplating ...

2021-6-27  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. A separate EW for the high Cu low Au Ag solution would be used.

Separation of copper from gold mixture

2008-3-9  A. You may precipitate the copper out of the copper sulphate solution by inserting a metal that is more reactive than copper, such as magnesium or iron. Copper metal will precipitate, but the magnesium/iron will dissolve and you will ultimately be left with a solution of magnesium or iron sulphate. This is known as cementation.
