separation of copper
Improved separation of iron from copper and other elements by
The separation is much better than the customary one with 3.5M hydrochloric acid. Columns containing only 8.8 ml (3 g) of resin can separate traces or up to more than 1 mmole of iron(III) from more than 1 g of copper. Mn(II), Ni, Al, Mg and Ca are quantitatively eluted together with copper(II).

The Best Way to Separate Copper and Nickel
In the end, you can recover the metals by means of crushing, grinding, flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel. Acid leaching can dissolve and separate out copper while oxidizing the matte can be used to leach our nickel.

A hydrometallurgical process for the separation of aluminum
Evaluation of metal separation efficiency for PC-88A and PC-88A/TOA. As demonstrated in Fig. 3, oxime-type Acorga M5640 extractant completely extracted copper within the pH range of 1.5–2.0 without extracting the other three metals. Therefore, Acorga M5640 is the appropriate choice for copper separation.
