All three statements regarding magnetite ore of iron are correct. Magnetite is known as black ore, it has a high iron content ranging typically from 60% to 70% in good quality ores, and it possesses strong magnetic properties.

Magnetite (Fe3O4) is one of the main iron ores and is characterized by its dark color and magnetic properties, often being the highest quality iron ore due to its high iron content.

– Hematite (Fe2O3) is another major iron ore, typically reddish-brown and not magnetic. It usually has a lower iron content than high-grade magnetite.
– Magnetite is a ferrimagnetic mineral, meaning it is strongly attracted to magnets and can even become a permanent magnet itself (lodestone).
