How is iron extracted from hematite ore? | Yahoo

2006-6-14 · As a slag, the calcium is easily separated from the more dense molten iron. This is done simply by tapping the slag with an outlet. When cooled, the molten iron from the blast furnace becomes pig iron. It still contains a number of impurities; Sulfur . Phosphorus . Boron. These lower the iron's tensile strength and make it more brittle.

How Is Iron Extracted From the Earth? -

2020-3-26 · 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.
