1. Introduction. Iron, a ferrous metal, is the largest used metal in the world. Iron is widely used in various fields and steel making is the industry with the largest consumption of iron ore [1], [2].Since the 21st century, economic growth and social infrastructure construction have been developed rapidly in many countries.
Iron Extraction. The common ores of iron are its oxide, hematite, Fe 2 O 3, and magnetite, Fe 3 O 4. They can be reduced to iron by heating them with carbon in the form of coke. The coke burns in an exothermic reaction. At the high temperatures, the carbon dioxide reacts with more coke to make carbon monoxide.

The co-extraction of iron is a known problem in the extraction of vanadium, and the sufficient separation of vanadium and iron ions is desired. The aluminum concentration was reduced to 0.23 g·L −1 due to its removal by alum crystallization during the neutralization pretreatment; the concentrations of other impurities were very low.
Recovering iron and aluminum efficiently is the key route to utilize low-grade high-iron bauxite. Aiming to optimize the iron separating process and elevate both Fe and Al recovery ratio, three different Fe–Al recovery processes with different magnetic roasting (R), Bayer leaching process (L) and magnetic separation (S) orders were investigated. …
