Coal upgrading technology is developed to reduce moisture content from LRC (low rank coals) and raise the calorific value Coal drying technology is one of the methods Accounting for more than 50% of the world coal reserve lignite or brown coal may contain water 20-30% even up to 60%

LOW TEMPERATURE DRYING OF ULTRAFINE COAL by Chad L Freeland ABSTRACT A new dewatering technology called low temperature drying has been developed to remove water from ultrafine (minus 325 mesh) coal particles The process subjects partially dewatered solids to intense mechanical shearing in the presence of unsaturated air Theoretical analysis of the thermodynamic

A Comparison of Coal Beneficiation Methods Abstract Although iron pyrites and other minerals are removed from coal on an industrial scale almost exclusively by gravity separation methods at the present time other beneficiation methods are coming into use Among the developing methods froth flotation (1 2 3) is the foremost although the oil agglomeration method (4 5 6) is also promising

Coal was then continuously mined from the Telford Basin at a rate of approximately 2 Mt/year by open-cut methods up until 2015 when mining operations ceased The mining operation involved drilling blasting and removal of overburden and coal by shovels and trucks After mining the crushed coal was railed to the Port Augusta power stations where it was used as fuel contributing to the state's
