Abstract
The study of the kinetics of oxidative roasting of zinc concentrate and copper-zinc intermediate product at 400-900°C on a laboratory unit in a fluidized bed reactor showed that at temperatures up to 550-600°C there is practically oxidation of iron sulfides only, and at temperatures above 600°C there is a joint oxidation of all metal sulfides present in these concentrates.
