Coal Beneficiation

Coal Beneficiation an overview ScienceDirect Topics

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

COAL BENEFICIATION

Coal beneficiation technologies create cost-competitive, upgraded coal feedstocks that increase the value of existing coal assets as power plant fuels, address technical barriers that limit exports of domestic coal, and create additional revenues from non-traditional coal-based carbon products.

The dry separation methods for coal beneficiation have been regaining attention in the past decades. A number of improved or newly designed devices have been developed—one of them is a negative pressure pneumatic separator (NPPS). The said method of separation is based on the differences in the physical properties between coal and gangue minerals, such as the grain density, size, and shape.
