Iron Ore Pellets
What are particles? Iron ore pellets, like concentrates, are raw materials for the manufacture of iron, which is pulverized and ground into pellets ranging from 0 to 100 microns for supply to industry as pellet feed. Green pellets and hardened green pellets are used in the direct reduction process to produce iron. Raw materials for […]

Iron Ore Pellet
From 1965 to 1985, the percentage of iron feed composed of pellets increased from 8% to 32%, mainly at the expense of lump; sinter percentage dropped only modestly, from 53% to 48% [11, 12]. The United States, in particular, has made a dramatic shift in ironmaking feed—36 million metric tons of pellets compared with only 5.1 of sinter in 2010 [3].
