IntroductionPropertiesUsesHistoryFormationResourcesMiningProcessingBlack coal can be used without any processing, but is usually crushed, screened and sorted according to customer requirements. Sometimes it is also washed to remove any pieces of waste minerals that do not burn. This improves the quality and reduces the production of ash when the coal is burned. To wash the coal it is placed into tanks with liquids...![](/images/31.jpg)

Coal Cleaning an overview ScienceDirect Topics
Chemical cleaning methods are better than physical methods because chemical processes can remove finely distributed minerals and organically bounded chemical species. The chemical cleaning methods can be divided into two categories: use of chemicals that dissolve minerals, usually called as UCC, and solvents for dissolving the coal-like matter, usually called AFC.

9/8/1982· The large size of installations introduces other operating and environmental uncertainties. For instance, the largest Stretford sulphur removal process to be built in the USA (105 ton day –1) has been contracted for the Great Plains gasification process (Stantberg, 1982).However, the Stretford process will not remove COS, and the presence of HCN will

Coal Cleaning an overview ScienceDirect Topics
Coal cleaning is used to remove ash and pyritic sulfur in coal [26,27]. Mercury that coexisted as pyrite can be removed by coal cleaning before combustion. The process of cleaning coal is a wet one, using large quantities of water (i.e., thousands of gallons per minute). As a result, vast quantities of dirty (fine rock-laden) water are

Coal Washing Encyclopedia
The cleaning process consists of a number of steps that results in a product that is specifically suited to the needs of particular consumers. Among the earliest of these steps is crushing and sizing, two processes that reduce the coal to a form required by the consumer. The next step in coal preparation is a washing or cleaning step.

An alternative is longwall mining, which uses a large cutting blade to slice across the coal layer to remove the coal seam. The coal is then transported to the surface on a conveyor belt. After the coal is mined the machine is dismantled and relocated to another section of the mine allowing the roof to collapse behind.
