Kinetics of cobalt sulfate dissociation and its interaction with iron sulfide
Authors:
Abstract
The dissociation of cobalt sulfate and its interaction with iron sulfide are important for understanding the process of sulfatizing roasting of cobalt-bearing pyrite concentrates. The dissociation of cobalt sulfate in a nitrogen atmosphere in a fixed bed begins at 730°C, in an atmosphere of air and oxygen, respectively, 15 and 30°C higher. According to A. V. Vanyukov, the beginning of thermal decomposition is observed at 692 and at 720‑770 °C, and proceeds actively. According to other data, the decomposition of cobalt sulfate at 2‑3 hour heating in a current of air occurs already at 600 °C. Information on the kinetics of dissociation of cobalt sulfate in the fluidized bed in the literature is absent.
