Should the pelletizing of iron ore concentrate be considered a mining or a metallurgical activity? Louis Bienvenu, Mining Engineer Ministère de l''Énergie et des Ressources naturelle. In the steel production process, there are two main steps: the extraction of iron ore and its transformation into steel. But what about pelletizing?
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
Apr 17, 2013· Answers. because of the fact maximum iron ore is iron blended with oxygen or sulfide. heating to melting produces pig iron which may be extra subtle to make metallic or forged iron. the common ore of copper is a mineral that''s a mix of copper and iron. so only heating does no longer something to purify the two metallic.
