Use of Oxygen-Enriched Gas for the Oxidation of Acid and Fluxed Ta...

By: Larry A. Haas

The U.S. Bureau of Mines, in cooperation with Cleveland-Cliffs, Inc. (Hibbing, MN), investigated ways of enhancing the quality (compressive strength, after-tumble and reducibility) of domestic acid and fluxed magnetite pellets by m o d i g the oxygen content during the preheat and induration periods of the firing operation.
