The study reports the results of laboratory investigation to develop the method of the recovery of zinc in either a metallic or oxide form from production waste containing about 70% Zn and the compounds of Fe, Cd, Cu and Mn. Laboratory tests were conducted in two directions using, respectively, a pyrometallurgical method and a hydrometallurgical method. The scope of the investigation encompassed the obtaining of zinc oxide on the induction furnace extraction filters, while for the hydrometallurgical processes – leaching, electrolysis and solvent extraction. The most effective method has been considered to be leaching with a 1M HCl solution, because of the highest Zn concentration after the electrolysis process and a low level of process difficulty.
