Benefits of Agglomeration in an SX-EW Process for Copper

The copper solution resulting from heap leaching still contains impurities that must be removed before a pure copper product can be produced. For this, an extractant is needed. The process of extracting the copper from the solvent is typically carried out in mixer-settlers which use different types of extractants to purify the copper in two stages.
