Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

Aerofall Mill in a Mining Operation ball mills supplier

An Aerofall mill is a type of autogenous grinding (AG) mill. It is a machine that uses a tumbling mill drum filled with ore and steel balls or rods to grind and reduce the size of the ore particles. The grinding process occurs due to the impact and abrasion of the ore particles against each other and the steel balls or rods within the drum.
