Zinc and Lead Solvent Extraction and Electrowinning
Solvent extraction is a purification (Kaya et al. 2020) and the separation process between two immiscible liquid phases, where two or more components are separated based on their unequal solubilities (Kaya 2019).The objective of this process is to transfer a solute from one liquid (feed solution) to another liquid (immiscible solvent).
