Samples of coal and coal process waste were provided from a number of coal operations and projects from queensland, new south wales and one site in indonesia. The resulting case study sample set comprised a total of 125 samples, including coal, rejects and tailings from a range of locations, with varying geochemical properties and coal rank.

Coal refuse is usually composed of rock fragments derived from interseam shale or siltstone partings and waste rock materials from above or below the seam. The refuse shares many properties with the associ-ated coal seam.
These samples include raw coals, prepared coals, and waste coals from coal preparation. To understand the geochemistry and cleaning behavior of these coals, these samples were subjected to an integrated series of analyses described here, including microanalysis of coal constituents and bulk sample chemical analysis.
For the geochemical characterization, the applied methodologies were proximate analysis for the determination of moisture contents and ash yields of coal waste samples, in accordance with iso standards (iso 589, 2008, iso 1171, 2010, respectively), carbon content determination by leco analyzer, and inductively coupled plasma mass spectrometry (icp-ms) for the determination of major and trace elements in waste samples and their water leachates.
With coal gangue and high alumina refractory solid wastes as raw materials, needle‐like mullite powder, with an average diameter of about 1 μm, was synthesized at 1300°c by using the conventional solid‐state reaction method. Mullite ceramics were derived from the inexpensive needle‐like powder.
Plant establishment on these sites is often impeded, or even precluded, by the physical and chemical properties of the waste.
