METHOD OF SULFATING COBALT Russian patent published in 2006 - IPC C22B1/04 C22B1/06 C22B23/00

Abstract RU 2285732 C1

FIELD: metallurgy of non-ferrous metals; plants for production of cobalt, copper, nickel and other metals and their compounds by sulfating non-ferrous metals.

SUBSTANCE: prior to roasting with mixture of sulfur dioxide and oxygen, preliminary stage of oxidizing roasting of pyrite concentrate by oxygen-containing blast is carried out at ratio of 0.42-0.98 nm³O₂ per kg of sulfur; procedure is continued for 2-68 s.

EFFECT: considerable increase of rate of roasting; increased degree of sulfating of cobalt by approximately 8%.
