Abstract: The rapid growth of coal production is supporting China's economic development. This paper discusses significant developments of coal preparation industry in China. The development direction of low-quality coal resources is also described, including the comprehensive utilization of resources and green coal preparation. Coal preparation may shift from the simple separation and production of highquality products to a comprehensive utilization of associated resources and lowquality coal. Green coal preparation is a new concept and involves a highly efficient coal preparation method based on the water cycle and comprehensive utilization of resources. This paper also describes a technology that transforms coal (mineral) resources (including natural, secondary, and artificial resources) into useful products (including raw materials and fuel) by separation, extraction, and processing for an eco-friendly approach to using secondary resources.
