The Principles of Processing Siderite Ores with a High Magnesium Oxide Content

Abstract:

Due to the depletion of high-quality iron ore, it is becoming ever more urgent to involve the ores which, for some reason or other, could not be used in metallurgy, or were used in limited quantities. For example, the siderite ores of Bakalsk deposit (Chelyabinsk region, Russia, stocks of more than 1 billion tons) are of very limited use in the blast-furnace practice because of the relatively low iron content (29% on average) and high magnesium oxide content (11-15%). At present, the technology of obtaining calcined siderite concentrate (CSC) from the ores of Bakalsk deposit includes raw ore roasting (fractions 10 - 60 mm) in blast furnaces at temperatures above 1000⁰С, and dry magnetic separation.
