Thermal treatment of Indonesian lignite washery tailing

23/07/2015 Thermal treatment of Indonesian lignite washery tailings (LWT) was investigated in this study using TG–FTIR at different heating rates of 5, 15, 25, 35, and 45 °C min −1.After a first drying stage, two main pyrolysis stages appeared, i.e., stage II (300–600 °C) and stage III (700–800 °C), corresponding, respectively, to low-temperature evolution of volatile matter and further

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.

MANAGEMENT OF TAILINGS: PAST, PRESENT AND FUTURE

Most tailings can be thickened mechanically, some to a paste or filter cake consistency. However, clay mineral-rich tailings, such as coal tailings, mineral sands tailings, tailings from some oxide ores, and residue from the processing of bauxite, nickel laterite and oil sands, are difficult to dewater mechanically,

"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
