Separation of copper from gold mixture

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.

Extracting Gold | HowStuffWorks

­ Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.

Gold Plating on Copper: Diffusion barrier needed?

A. Gold can be plated directly over copper but the copper will migrate into the gold layer over time. Copper is usually plated with nickel before being plated with gold and gold can be plated to almost any thickness from only a few micro-inches up to whatever thickness you are likely to want.

Top 3 Gold Gravity Separation Equipment: What Are They

Gold panning, or simply panning, is one of the most basic and simplest gravity separation methods to extract gold from a placer deposit using a pan. Scoop placer gold ores in the pan, and agitate gently in water until the gold sinks to the bottom of the pan. For amateur gold miners, gold panning is economical and efficient.

How To Separate Gold And Copper?

How Do You Separate Gold And Copper? The most common way to remove copper from gold ore in leaching is through the use of cyanide. Cyanide will react with the copper and form a compound called "cyanide copper". This compound can be then be separated from the gold using a variety of methods, such as flotation or gravity separation.
