    Little was known about the influence of the flame. A "reducing" flame, or one with less oxygen supplied for burning, might produce a bluish-green because the iron in the sand might then be reduced to one of the bluer iron oxides - an excess of air might make the oxidized green iron oxides predominate.

  • Hot Dip Galvanizing Design Considerations

    The use of old and new steel or castings and rolled steel in the same assembly should be avoided, when possible. Where assemblies of cast iron, cast steel, malleable iron and rolled steel are unavoidable, the entire assembly should be thoroughly shot or sand blasted prior to pickling in order to produce a galvanized coating of acceptable quality.

    Titanomagnetite sand comes from volcanic deposits which have been eroded by coastal action and dispersed along the coast by littoral currents. Taharoa has both wind and waterborne deposits in dunes reaching up to 90 metres (m) in height. The ironsand is mined by a floating cutter suction dredge.

  • Iron ore - Wikipedia

    Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
