Utilization of coal gangue for the production of brick

2016-6-8  The LOI of the coal gangue reaches as high as 19.53 wt%, which is attributed to the high content of organic matter, as well as clay minerals, calcite, and dolomite in the coal gangue. Besides, the coal gangue has a calorific value (Q gr,v,d) of 3.01 MJ kg −1, determined according to Chinese National Standard GB/T 213-2008. Therefore

Extraction of alumina from alumina rich coal gangue by a

2020-4-29  Coal gangue is an industrial solid waste produced by coal mining and processing [1–3]. The average production of gangue accounts for 10–15% of raw coal production [4,5], making coal gangue one of the biggest solid wastes in China. At present, utilization ratio of coal gangue can reach about 60% in some countries.
