  Quality requirements of iron ore for iron production

  201511 · H 2 and CO gases react with Fe 2 O 3 in the iron ore and convert it to metallic iron, generating H 2 O and CO 2, which exit at the top of the shaft furnace. For production of cold DRI, the reduced iron is cooled and carburized by counterflowing cooling gases in the lower portion of the shaft furnace.
