Separating Copper from Gold (electroplating

Separating Copper from Gold (electroplating) (8 replies) Helena Russell 6 years ago I am currently separating and extracting gold from margin ore dump (Mod) using the following processes: leaching, carbon in pulp, elution (zadra process) and electro winning. My final product (sludge gold) is contaminated with excessive copper.

Separation of copper from gold mixture Finishing

Mar 09, 2008 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.

How I can separate gold from copper? Quora

All Gold apart from 24c pure Gold contains Copper as an addition. If so it is going to be difficult.You can’t do it at home. You need to use 50% Nitric Acid.The acid will dissolve the Copper but not the Gold. Then filter off the Copper Nitrate and you are left with a sludge of Gold.
