Effective Processing of the Iron Ores
Iron ores are the primary source for iron melting. Almost all of the iron ores are transformed into steel, cast iron and iron based alloys. Cast iron and steel are the fundaments of modern industries. The processing of iron products goes in a few stages. Usually it is mining, mineral processing, agglomeration, casting, depuration.
