  • Iron Ore Geoscience Australia

    High-grade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but

  • Iron ore extraction techniques ScienceDirect

    1/1/2015· Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this

    Where the coal contains shale, intrusion, or other contaminants, the Flipscreen can process the coal to a higher grade and therefore achieving a premium in approximately eight seconds per bucket. The WL3000 will process 30 tonnes of coal per 76-second cycle, resulting in an hourly rate of 1,410 tonnes per hour. In the case of iron ore mining where crushing is required, the WL3000 computer can
