What Is Iron Ore Beneficiation? (with pictures)

Water molecules are removed as part of iron ore beneficiation. One of the approaches to iron ore beneficiation first involves a basic screening or filtering of the ore and then crushing it using equipment like a jaw crusher to break up the rock from its natural state down to individual block or rock sizes with dimensions of length or height no greater than 3.3 feet (1 meter).
