separation and classification of iron

Iron | Fe (Element) - PubChem

Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6% of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). The minerals taconite, limonite (FeO (OH)·nH 2 O) and siderite (FeCO 3) are other important sources.

Ore Beneficiation - an overview | ScienceDirect Topics

In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock. Secondary crushing and screening can result in further classification and grading of iron ore.
