Ore has a crucial effect on water and tailings quality. Ore sorting targets to remove the non-valuable material in the beginning at a coarse particle size to avoid the processing of barren material below the cut-off grade, where the processing would cost more than the value of the metal (Duffy et al., 2015; Gülcan and Gülsoy, 2017).

Due to Lignite's brittleness it breaks down during the washing process to small sizes and is often dealt with during the sand washing stage, however in some areas where large pieces of lignite are present it must also be removed from the gravel fraction. The removal of Lignite provides an uncontaminated sand and gravel for further processing.

The lignite shows a combustion profile with the main peak between 500 and 700 °C. The maximum weight loss rate was observed to be 0.59%/°C at 606 °C. Lignite has a boarder combustion zone and higher weight loss which may depict thermal decomposition and oxidation, including de-volatilization, char gasification, and …

Mineral identification in coal is complex because not only its content in coal is relative lower than organic matter, but also it is closely related with organic matter in various modes of occurrence [1], [4], [8], [9].Additionally, organic matter in coal dilutes the content of the minerals and this leads to difficult to identify mineral using X-ray diffraction …
