Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore

The Guangling hematite ore sample consisted of % Fe 2 O 3 % SiO 2 % Al 2 O 3 % FeO % CaO % MgO % Na 2 O and % K 2 O Harmful elements such as phosphorus and sulfur were present in only low quantities This hematite ore contained a small amount of magnetite; hematite is the precious form of iron minerals

Magnetite Concentration Methods

Iron ores to be commercially profitable must carry a high percentage of iron the low limit being apparently between 20 and 25 per cent iron present as magnetite This results in a low ratio of concentration and a comparatively small quantity of tailing and a large percentage of iron in the tailing may represent but a small loss when compared with the total iron in the ore The
