China is, and in the coming decades should continue to be, the largest producer and user of
coal in the world. The high volume of coal usage in China has focused attention not only on …

The rapid economic development in China places a large demand for energy, and as a
result, thermal power plants in China are producing an enormous amount of coal fly ash …

A cascade extraction method was constructed by combining alkali desilication with
carbonation and acid leaching to achieve efficient separation and comprehensive recovery …

Owing to the continuous high demand for energy, huge amounts of coals are consumed
every year in China, giving rise to large volumes of coal combustion products (CCPs) from …

Calcium silicate slag is an alkali leaching waste generated during the process of extracting
Al 2 O 3 from high-alumina fly ash. In this research, a cementitious material composed of …

The reaction behaviours of Al 2 O 3 and SiO 2 in high alumina coal fly ash under various
alkali hydrothermal conditions were studied. The means of XRD, XRF, FTIR and SEM were …

The mineralogy and trace element redistribution in the processes of extracting alumina from
high aluminum fly ash in an industrial-scale production line (ISPL) in Inner Mongolia, China …

To realize the comprehensive utilization of coal-fired industrial solid wastes, a novel high-
strength board was prepared from calcium silicate slag, fly ash, and flue gas desulfurization …

Calcium silicate slag (CSS) is an industrial waste residue produced by the extraction of Al 2
O 3 from high-alumina fly ash. CSS, along with cement, is used as a cementing material to …

The efficient utilization of aluminum and silicon resources simultaneously is expected to
reach by the process of alumina extraction from coal fly ash via Na 2 CO 3 activation-acid …
