Abstract
The author state feasibility of deep sulfidation of rebellious oxidized lead and zinc minerals under calcinations with pyrite concentrate in the aqueous vapor environment. It is shown that interaction between oxidized lead and zinc compounds and iron sulfide in the superheated vapor with sulfide formation takes place at the solid-gas interface, namely, MO–H2S–under sulfidation of heterolyte and beudantite; PbSO4–H2S–under sulfidation of plumbojarosite.
