  • Overview Labrador Iron Ore

    The iron ore deposits in the Labrador City area occur as specular hematite and magnetite, generally in the ratio of 65:35. IOC has mineral reserves and resources of 1.3 billion tonnes and 1.8 billion tonnes, respectively, with an average grade of approximately 38% iron.

  • Recovering Iron from Iron Ore Tailings and Preparing

    Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.
