Abstract

Roasting the sulfide-zinc concentrate with a high silver content is investigated by thermogravimetric and differential thermal analyses in the mode of polythermal heating. It is shown that roasting at 630 ± 10°C makes it possible to obtain mostly sulfate roast, which is most suitable for the effective recovery of zinc and other components.
