    Determination of Iron in a Hematite Ore

    Introduction. The determination of iron in oxide ores is determined by either precipitation of hydrous ferric oxide. and ignition to Fe 2 O 3 or by the reduction of dissolved Fe (III) to Fe (II) followed by the titration with a. standard oxidizing agent such as the dichromate ion, Cr 2 O 72- (Rice, 27).

  • What is Iron Ore?

    What is Iron Ore?

    Jul 28, 2017 Iron ore refers to rocks or minerals from which metallic iron is extracted for commercial use. These minerals appear dark grey to rusty red in color, and are usually rich in iron oxides. Iron occurs in these ores in the form of such chemical compounds as hematite, magnetite, siderite, limonite, or geothite. Even though iron is the fourth most ...
