· Manganese ore is important for several reasons: Manganese is an extremely hard and brittle silvery grey mineral. It is always found with iron, laterite, and other minerals. Manganese alloys are an important component of steel production, and steel is one of the most important indicators of a country’s industrial economy’s growth.

· Iron ore is a rock from which the metal iron is extracted. About 98% of the world’s iron is used to produce steel. Pure iron is an element and a soft grayish-white metal. Other than meteorites that fall from the sky, iron is never found by itself in nature. Most iron is part of minerals that contain other elements.

· Iron ore accounted for 93% of the metals mined in 2021, with 2.6 billion tonnes extracted from the ground. It’s important to note that this is ore production, which is typically higher than metal production since metals are extracted and refined from ores. For example, the iron metal content of this ore is estimated at 1.6 billion tonnes.
