Theoretical aspects of parallel coal processing circuits ...

1989-12-1  TYPICAL PARALLEL COAL PROCESSING CIRCUIT Let us consider a typical coal processing circuit where processed size ranges of a coal are blended with middlings or raw coal as shown in Fig. 2a (Mishra and Klimpel, 1987). The blending is performed to control the overall product ash at a specified ash content.

Coal-A is the reject/tailing coal from fines circuit (−0.5 mm) i.e. froth flotation process, which is presently used for foundry application. Coal-B and Coal-C are the rejects from the coarse circuit (−13 + 0.5 mm) i.e. dense medium cyclone. Coal-B is also known to be coal middlings, is used for power generation. Coal-C, also called high ...

Fine coal processing with dense medium cyclones

2021-9-11  Beneficiation of fine coal, nominally below 0.5 mm, with dense-medium cyclones was implemented as long ago as 1957 and cyclones are still being used to process fine coal today but the history shows that the application of cyclones in fine coal processing has not been nearly as successful as in the processing of coarser coal.
