Iron ore that has been processed to raise its iron content and lower impurities like silica, alumina, and other gangue minerals is known as concentrated iron ore. Iron ore concentration is the term for this process, which usually include crushing, grinding, and isolating the valuable iron particles from trash. To put it briefly, iron ore concentrate is the end result of beneficiation

The ore is crushed and sized to, e.g., 6.3–31.5 mm fraction if it is used as lumpy ore in blast furnaces. Pure, thoroughly sized and easily reducible lumpy ore is also used as a supplement with sinter and pellets. After mining, most of the iron ore is produced as fine concentrates through crushing, grinding, and screening.
