REDUCTION METHOD OF METAL AND OXYGEN COMPOSITIONS Russian patent published in 2009 - IPC C22B5/10 

Abstract RU 2360982 C2

FIELD: metallurgy.

SUBSTANCE: at reduction of metal and oxygen composition effect as reducer, herewith at first stage gaseous CO is passed into reaction chamber, containing specified composition of metal and oxygen. In conditions, providing conversion of CO into solid carbon and carbon dioxide, formed solid carbon is introduced into metal and oxygen composition. At the second stage solid carbon, which is introduced into metal and oxygen composition at the first stage, reduces metal and oxygen composition. Additionally at the second stage it is, at least, the first material- promoter, conducive reduction of specified metal and oxygen composition. Additionally the first material- promoter contains the first metal- promoter and/or composition of the first metal- promoter.

EFFECT: invention provides implementation of process at comparatively cold temperature with formation of less volumes of noxious exhaust gas.
