How are metals extracted from ores? What are the various

Steel and iron are extracted by taking iron ore and placing them in a crucible with a different material on top to attract the oxygen in the ore, known as flux. They heat the crucible and the flux grabs the oxygen that becomes available, leaving only pure iron that can then either be added to for alloys and to make steel or simply poured raw.
