Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore ...

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH4 from COG and produce separated magnetite from low grade hematite. In this work, lowtemperature hydrogen reduction of hematite ore fines was performed in a fixedbed reactor with a stirring apparatus, and a laboratory Davis magnetic ......
