    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 oreCopper processing is a complicated process that begins with mining of the ore (less than 1% copper) , This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impuriti The copper matte created by the smelting furnace contains 58-60% copper.

  • Life cycle assessment of iron ore mining and processing 619 Many minerals contain iron, but the primary sources of iron ore minerals used to make iron and steel are hematite, magnetite .The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant Crushing is a dry process whereas grinding is generally performed wet and hence is more energy.
