Magnetic Iron Ore Mining Methods
Magnetic and Gravity Methods in Mineral Exploration: the .
Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
How Is Iron Extracted From the Earth? | Reference.com
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.
