Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

PURIFICATION OF IRON ORE (BY MAGNETIC SEPARATION METHOD ...

Iron has been known since prehistoric times. Indians were familiar with its extraction. It may be called the king of metals. The Ore of Iron can easily be separated from Gangue by this method. Large amount of ore can be purified by this method. It has two rollers, one is magnetic roller & other one is nonmagnetic roller. When ore is dropped on the magnetic roller, it moves through conveyers ...
