What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities Through coal preparation, a uniform product is achievedRecently, three major processing technologies of coal tar have been employed (Fig 1)The first technique is separation (Song et al, 2019; Sun and Zhang, 2017), which is mostly adopted to process and produce light oil, phenol oil, naphthalene oil, and modified asphaltThis process route includes homogenization of coal tar; Carbon precursors in coal tar: Extraction and preparation of carbon

When coal seams are near the surface, it may be economical to extract the coal using openpit mining (also known as opencast mining) Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploitedDepth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction However, many coals extracted by using these two methods need washing in a coal preparation plant Surface mining: The mining technique is used when the coal seam is present near the Commonly used mining techniques to extract coal ICSC
