Macerals are the basic constituents of coal that can be distinguished and identified under the microscope. Depending on the difference in optical properties, the macerals are divided into four maceral groups, including liptinite, vitrinite, huminite and inertinite. These maceral groups not only affect coal mining and utilization but also play different roles in coal beneficiation. According to the different properties of maceral groups, they can be separated (or enriched) to provide high-quality raw materials for the coal industry. This review briefly introduces the international maceral classification system and reviews in detail the role of maceral groups in coal beneficiation combined with their properties.
