Hydrogen Reduction Of Hematite Ore Fines To Magnetite

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 CH 4 from COG and produce separated magnetite from low grade hematite. In this work low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus and a laboratory Davis magnetic .
