How Is Iron Extracted From the Earth Reference

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.

Environmental Risks From Mine Tailings

Aug 10 2018 · Sulfuric acid is sometimes produced when water interacts with tailings or it can be a by-product of ore processing. As a result highly acidic water leaks from the tailings and disrupts aquatic life downstream. Tailings from copper and uranium mining often produce measurable levels of radioactivity.
