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.

Global progress towards the Coal: Tracking coal reserves, coal prices, electricity from coal, carbon emissions and coal phase-out

Gondwana Research
Coal remains a significant energy source globally, with the United States holding a substantial portion of the world’s coal reserves but it creates the dangerous effects of global warming. Despite its abundance, questions arise regarding the accessibility and environmental impact of coal reserves.

Coal and Coal Products

2004
Coal is a very special material in that, unlike the minerals which we have hitherto considered, it does not come with any defined composition. Its principal element is carbon, but the proportion of carbon and its bonding can vary considerably, which partly defines its rank.
