The chemical formula for magnetite is Fe 3 O 4. However, there is another formula for magnetite - FeO. Fe 2 O 3 - which is a combination of the formulas for wustite ( FeO) and hematite (Fe 2 O 3 ). This means that magnetite consists of one part of wustite and one part of hematite. Magnetite is the most magnetic mineral that is found on Earth.

Mar 30, 2022Introduction Banded hematite quartzite (BHQ) is a low-grade iron ore with an iron content ranging between 37% and 44%. India has 22,487 million tons of hematite iron ore resources, and 5422 million tons in the reserve category. Karnataka State, mainly the Sandur schist belt, accounts for about 11% of this hematite iron ore resources.
