【 摘 要 】

This paper presents the results of the kinetic studies of the zinc sulfide concentrate oxidation with the addition of inert, ZnO-containing materials. It was observed that about 15% of zinc oxide addition, obtained from steelmaking dust, improves the rate and maximum degree of oxidation of the concentrate. Kinetic equations of the process were determined, and the activation energy for various additions of inert material was calculated
