In some cases this is done chemically. Process in which the extraction of metals from ores is called: A. metallurgy. BloodOre. Answer. Spell. 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. The second process is to smelt the ore, which operation is performed in " blast furnaces." EASY. Terms in this set (7) Ore. Theses are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. Extraction of Iron from its ores.
