Trace Elements in Coal Gangue: A Review | IntechOpen

13-04-2017· Coal gangue is one of the largest industrial residues. It has high ash content, low carbonaceous content, and heating value. Meanwhile, it has some trace elements. Large quantities of coal gangue cause serious environmental problems by polluting the air, water, and soil as well as occupying a tremendous amount of land. Now, coal gangue utilization is a matter of great concernPower Generation from Coal Gangue in China: Current,This paper provides an overview on the current status of power generation in China using coal gangue. The government regulation towards the use of coal gangue for power generation is introduced. Emission of pollutants and low thermal power plant efficiency are the two major problems for the power industry firing coal gangue. Particulate matter emission control is a problem due to the high ash,Potential ecological risk assessment and prediction of,,Coal gangue is a heterogeneous material, and the total concentrations of heavy metals (Cd, Pb, Cu, Cr and Zn) in the surface (i.e., weathered) of the coal gangue dump were higher than deeper portions. In order to make the gangue samples to be representative, four samples from different depths (depth=2, 3, 4 and 5m) of the coal gangue dump were,

It is thus distinct from overburden , which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings , which is rock already stripped of valuable minerals.Coal in China - Wikipedia,Coal reserves. As of the end of 2014, China had 62 billion tons of anthracite and bituminous, and 52 billion tons of lignite quality coal. China ranks third in the world in terms of total coal reserves behind the United States and Russia. Most coal reserves are located in the north and north-west of the country, which poses a large logistical problem for supplying electricity to the more,
