Main scientific results

1. Based on the conducted studies, a scheme for processing zinc sulfate solutions with a high content of impurities is recommended and initial data are provided for the design of an experimental installation for complex purification of zinc sulfate solutions with a high content of impurities, followed by zinc electrolysis.

2. Developed technological regulations for the design of the pilot plant in accordance with the proposed technological scheme of deep purification from impurities of zinc sulfate solutions of atmospheric oxidative leaching of low-grade sulfide concentrates.
