Brown Coal Processing

  • Coal | Geoscience Australia

    Lower quality coal such as sub-bituminous or brown coal can be refined to remove moisture and other impurities. This increases the efficiency of the coal as a fuel and reduces emissions of greenhouse gases and other pollutants, when the coal is burned. In Victoria the brown coal is upgraded by the Coldry Process.
