Abstract

The zinc ferrite cake, which is generated during the wet extraction of zinc calcine at PJSC Zinc Plant (Chelyabinsk) has a complex mineral composition. The main mineral phases in the cake are basically represented by zinc ferrite, zinc sulfate, plumbojarozite and copper oxide. The cation-exchange resin leaching of metals from zinc calcine and zinc cake (obtained at the acid leaching stage) is a promising method in which KU‑2–8 ion exchanger in H‑form can be used as reagent. In the paper it was found that a significant part of the ZnFe2O4 (60 %) can be dissolved under mild conditions at pH=1 and 25 °C while the total zinc recovered from the calcine by the cation-exchange resin leaching reaches 98 %. The activity of the zinc cake is higher than that of the synthesized zinc ferrite sample
