More than two-thirds of coal in China is present in dry areas and cannot be separated by traditional wet coal preparation techniques. Dry coal beneficiation is an effective technique to realize coal separation and upgradation, as it does not consume water, has a low cost and is pollution-free. In this study, an air dense medium fluidized …

1. Introduction. China is the world's largest coal producer and consumer. Coal has accounted for more than 60% of the electricity generation over years, and it will remain a major energy source in the foreseeable future (IEA, 2020, Luo et al., 2021).Coal combustion has generated large quantities of ash that need to be properly managed.

Although traditional physical coal washing method could reduce the ash yield in coal to a great content, the coal beneficiation plant in China could only reduce the ash yield to about 10% at present [14], [15]. On the other hand, the big environmental problem and limited transportation budget due to the utilization of this coal force us to seek ...

Coal Beneficiation. Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

Abstract. Coal is a physical mixture of high carbon value coal and rejects. Coal beneficiation is nothing but the separation of these high carbon value coal from rejects (noncarbonaceous material) in a coal body. Although the theoretical knowledge of coal beneficiation is available aplenty in coal preparation books; it is essential that …
