Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and fluegas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.
Flyash and coal gangue are the two main industrial solid waste in China. The chemical compositions (shown in Table 1) were SiO 2, Al 2 O 3, Fe 2 O 3 and some impurities. As the coal gangue is main solid waste for coal mining, one of the most common approaches to waste rock is to stack construction that encapsulate the most pyrite rich rocks in the core of a waste rock stack (Lottermoser, 2003 ...
