is magnetite smelted to get hematite

  • The ancient art of smelting iron Anita Chowdry

    Jul 30, 2014 Long before the development of industrial smelting processes, craftsmen set up small furnaces or Bloomeries to make useable iron or steel from natural local iron ores, such as Hematite, Siderite, or Magnetite. There has been a resurgence of interest in these processes as a kind of experimental archeology.
