Solvent extraction (SX) of zinc is useful for the recovery of high purity zinc from the leaching solutions of its sulphide minerals, several low‐grade ores, and secondary materials. The technique is fast, environmentally sustainable, and can be tailored to treat aqueous solutions of diverse compositions.
