|
|
It is the finest iron ore with very high content of iron upto 70%.
|
|
|
It has a slightly lower iron content than hematite (50-60%)
|
Detailed explanation-1: -Magnetite is the finest iron ore with a very high content of iron up to 70 per cent. It has excellent magnetic qualities, especially valuable in the electrical industry. Hematite ore is the most important industrial iron ore in terms of the quantity used, but has a slightly lower iron content than magnetite.
Detailed explanation-2: -Magnetite is the best quality of iron ore and contains 72% pure iron.
Detailed explanation-3: -Magnetite is the finest ore among all the ores of Iron. Magnetite ore comprises of seventy per cent of iron. The magnetic properties in this ore are appreciable. Fe3O4 is the chemical formula of magnetite ore. Magnetite (Fe3O4) is reduced to Ferrous Oxide (FeO) and then later Iron is extracted from its oxide.
