A full sequence of investigations was performed with a purpose to develop adequate extraction technologies for the purification of a few typical industrial, both sulphate and chloride, heavily contaminated zinc(II) solutions. These covered: i) independent measurements of individual cation extraction versus pH and extraction isotherms with commercially available extractants, ii) the design of individual extraction systems for the chosen extractants, iii) the counter-current batch-wise full process imitations in a laboratory glass with the use of di(2-ethylhexyl)phosphoric acid (DEHPA) and di(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272), iv) pilot trial with the use of DEHPA, executed on train of mixer-settler type extractors, working continuously.
