Coal Processing and Use for Power Generation
As a result processing equipment that is used for coarse cleaning is not suitable for removing fine pyrite from coal. Flotation is the technique that best treats fine coal, however, due to similar surface properties of coal and pyrite, it is generally ruled out as an efficient cleaning method for pyritic sulphur.
