Flotation performance analysis on coal washery rejects

2021-5-8  Cleaning coal, especially washery rejects has posed a major challenge to the recovery of fine coal. 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.

Optimization of Coal Washery Tailings by Flotation

2019-10-17  Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings compared with raw coal.
