High Quality Content by WIKIPEDIA articles! Coldry Process is a coal upgrading technology developed in Victoria, Australia by Environmental Clean Technologies Limited to specifically beneficiate low-rank brown coal (lignite) and sub-bituminous coal by removing natural high moisture content and certain pollutants; harden and densify the coal; raise the calorific value of the coal to more than 5800 kcal/kg; and transform the coal into a stable, exportable black coal equivalent product for use by black coal fired power generators to produce electricity. The Coldry Process is a commercial method to achieve large scale beneficiation of low-rank coal without a need for government subsidy.
