Froth flotation is a better choice for processing coal washery rejects. In this study, flotation studies are attempted on the coal slurry received from Sudamdih coal washery, Jharkhand, India. A statistical design package (Minitab V17) was used to study the effect of process variables like collector and frother dosages on the responses.

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.

Coal washery rejects (CWRs) are a major byproduct produced in coal washery industries. We have chemically derived biocompatible nanodiamonds (NDs) from CWRs toward a wide range of biological applications. The average particle sizes of the derived blueemitting NDs are found to be in the range of nm. Highresolution transmission electron microscopy of the derived NDs depicts the ...

JHARIA REJECTS. Tata Steel coal washery rejects are produced as byproducts from its Jamadoba and Bhelatand Coal Preparation Plants. In both the plants, coal washery rejects are mixed with middlings to produce the end product '2PR or 2Product Rejects' as a part of the process. Quality of 2PR ranges from G13 to G17 equivalent of CIL coal grade.
