Iron Fe PubChem

Iron is a metallic element found in certain minerals, in nearly all soils, and in mineral waters. Iron is required for life. It exists in all living species, ranging from bacteria to humans. It can be found primarily in blood and it is an essential constituent of hemoglobin, cytochrome, and other components of respiratory enzyme systems.

Iron processing Ores Britannica

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
