How Is Iron Extracted From the Earth? - Reference

Mar 26, 2020· 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.

Optimization of Firing Temperature for Hematite Pellets

The pellet reducibility decreased with increase in magnetite phase percentage at different firing temperature. In iron ore pellet hematite is much more reducible than magnetite. It is highly desirable that the all the lower oxides (magnetite/FeO) of the pellet formed during heating should be oxidized to hematite during cooling cycle.

Meteorite Home Tests

Iron ore is the most common meteor-wrong. Magnetite especially is very magnetic (hence its name) and hematite may or may not be mildly magnetic. Both these minerals may possibly be distinguished from meteoritic material by a characteristic known as 'streak'. You can test the streak very simply.
