Recycling coal from coal gangue

Filtration + Separation, 2017
Coal gangue is not just solid waste, but also has the potential to yield useful energy. In China, a mining group and a local power plant power plant joined forces with a local university to look at ways to recycle coal gangue to improve the revenue, cut down on resource utilization, and reduce environment pollution.

Influence of pozzolanic activity of coal gangue on hydration products in coal gangue-cement system

2010 International Conference on Mechanic Automation and Control Engineering, 2010
Qualitative and quantitative analysis of the composition in the paste of complex cements have been determined by means of X-ray diffraction (XRD),differential scanning calorimetry (DSC) and directly-heating method. Results show that the composition of hydration products in coal gangue-cement complex system is similar to that in pure cement system, but ...
