METHOD OF PRODUCING COBALT OR COBALT-CHROMIUM THIOSPINEL Russian patent published in 2016 - IPC C01G51/00 C01G37/00 C01G1/12 C01B17/20

Abstract RU 2573522 C1

FIELD: chemistry.

SUBSTANCE: cobalt or cobalt-chromium thiospinel is obtained in a self-propagating high-temperature synthesis mode in an air atmosphere. The raw material used is a powdered mixture of cobalt sulphide CoS with the addition of cobalt metal powder for the synthesis of Co₃S₄, chromium for the synthesis of CoCr₂S₄ and crystalline sulphur, taken to the corresponding stoichiometric composition with a 5% sulphur excess.

EFFECT: invention simplifies the process, improves the efficiency, rate and environmental friendliness of the process.
