Development of the coal preparation technology under the strategy of attaining carbon peaking and neutrality

The way of the development of China's coal Preparation technologies is explored. Following an introduction to the state-of-the-art of China's coal industry, the paper goes to sum up the effective approaches that can be taken to effect energy saving, improvement of efficiency, upgrading of product and reduction of environmental pollution in raw coal pretreatment, washing and product handling processes. It is pointed out that against the backdrop of implementing the carbon peaking and neutrality strategy, the orientation of the development of the coal industry should be directed toward optimization of coal washing processes, use of large-sized washing equipment, realization of plant intelligentization, fine separation of coal slime and comprehensive utilization of coal and refuse. The study made may provide a new thought on the development and improvement of China's coal preparation sector.
