Gold(III) extraction and recovery and gold(III)/copper(II ...

2015-10-5  Gold/copper separation via MEUF. Copper is the metal that most frequently is found in alloy with gold. The results shown above on the extraction of the single metals indicate that the separation of gold and copper from a mixture could be achieved. Two procedures for the separation of the components of Au/Cu mixtures are presented in this section.
