After heat treating and HCl leaching, most of the quartz phase remained, the peaks assigned to kaolinite were no longer distinguished anymore, as shown in Figure 2, which correlates with a degradation of Al/Si compounds, the peaks belonging to iron mineral of siderite were getting weaker, especially at 750[degrees]C and 850[degrees]C treatments, which indicates an effective removal of Fe and Al compounds from the coal gangue, and most of the silicon phases were still retained.
