Optimization of Coal Washery Tailings by Flotation Process

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.

"The characterisation and leaching behaviour of coal

The tailings were characterised mineralogically and elementally, using analytical techniques such as XRD, SEM, Y-Spectrometry and ICP. A series of standard and modified leaching tests, based on the BEOP-31 standard, was used on the tailings to determine the release of four of the primary elements, and ten heavy metal elements, under different leaching conditions. The tailings were found to
