The discharge and accumulation of coal-based solid waste have caused great harm to the
ecological environment recently. Coal-based solid wastes, such as coal gangue and fly ash …

Among coal mining-related wastes, coal gangue (CG) is the heterogeneous waste
generated during the mineral processing or coal washing phase of coal mining. A thorough …

We collected street dust from Huainan, a typical coal-mining city in China, to investigate the
contamination features and health risks of heavy metals. Concentrations of Co, Cr, Cu, Pb …

Mixed combustion of carbon-rich fraction (RC) from coal gasification fine slag and corncob
char (CC) is an effective way of energy recycling. In this paper, the co-firing performance and …

The aim of the present study is to evaluate the potential ecological risk and trend of soil
heavy-metal pollution around a coal gangue dump in Jilin Province (Northeast China). The …

A rough estimate of the annual amount of sulfur, arsenic, mercury and fluoride emission from
spontaneous combustion of coal gangue in China was determined. The weighted mean …

This study aims to further reveal the properties of coal gasification fine slag (CGFS) and
provide the essential basis for the efficient and environmentally friendly utilization of solid …

A large amount of raw coal gangue (RCG) is generated during coal mining, which results in
serious environmental problems and vast land occupation. Considering the similarity …

Modified fly ash injection was installed at the outlet of selective catalytic reduction (SCR)
systems in a 1000 MW coal-fired power plant, reaching 94% mercury capture rate. Due to …

Spontaneous-combustion coal gangue aggregate (SCGA) has low physical properties and
strong water absorption capacity. Previous studies are mostly based on the principle of …
