SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place …

Thus, there is an escalating need to recover metals from e-waste for sustainable management of metal resources. Hydrometallurgical processing of e-waste, involving copper (Cu) leaching and its subsequent recovery from pregnant leach solution (PLS) via electrowinning, has emerged as an efficient strategy to close the recycling loop.

Usually, the metal elements in the ore are extracted from the solution by electrowinning to become the metal product after leaching and enrichment by extraction. The electrowinning process is energy-intensive because both the cathodic reduction reaction and the anodic oxidation reaction involve a large amount of energy consumption.
