    Thermogravimetric Analysis of the Reduction of Iron Ore,

    Iron ore with high hydroxyl content such as goethit is widely spread in Indonesia. Such iron ore is not used as feed in ironmaking industry. However due to limitation of primary iron ore reserve such material is an option to substitute the conventional iron ore. Unfortunately the characteristic of iron ore with high hydroxyl content is totally different to conventional iron ore.Amazon: Reduction Kinetics of Iron Ore-Graphite,,The rate of reduction of iron ore-graphite composite pellets under inert and reducing atmospheres has been investigated in a tailor made thermo-gravimetric packed-bed reactor.
