The phase mineralogy and leaching characteristics of some Indian coal fly ashes were
studied to assess their safe disposal in abandoned coal mines. Since, fly ash contains a …

Fly ash is a waste by-product obtained from the burning of coal by thermal power plants for
generating electricity. When bulk quantities are involved, in order to arrest the fugitive dust, it …

The physicochemical properties of fly ash from two kinds of coal-fired power plants were
studied. Three aspects were examined: the micro-morphology, the mineral composition and …

Bottom ash and fly ash are the by-products of coal in thermal power plants. They are the
combustion wastes and contain many elements that may harmful to the environment. The …

Leaching of ten elements–namely, Fe, Mn, Ca, Na, K, Cu, Cr, Zn, As and Pb–from four fly
ash samples collected from four different coal-fired thermal power plants in West Bengal …

Physical characteristics, chemical composition and leaching behaviour of a waste fly ash
from a coal-fired power station are reported. Particle size distribution was studied by the …

Chemical leaching using alkali and acid can be employed for effective separation of mineral
matter from difficult-to-wash Indian coals. In this article, an attempt has been made to …

This study presents the results of physical, chemical, and mineralogical characterization of
fresh and landfilled coal fly ash from Atikokan Thermal Generating Station, Ontario. The acid …

Coal-based power generation produces over 750Mt of coal ash per year globally, but under
50% of world production is utilised. Large amounts of fly ash are either stored temporarily in …

Abstract Characterization of the coal ash from a typical coal-fired circulating fluidized bed
(CFB) power plant in the Philippines was done by studying physical and chemical properties …
