Stabilized Coal Ash Artificial Reef Studies
Chemistry and Ecology, 1995Abstract In 1989, an experimental stabilized coal ash reef was deployed in Poole Bay off the southern coast of the UK. Three different mixtures of pulverised fuel ash, gypsum, flue gas desulphurisation sludge and cement were used along with concrete controls. the aim was to study the environmental compatibility of the reef materials through heavy metal

Retention of boron by coal ash
Environmental Science & Technology, 1982Adsorption of boron by the hydrous oxides of aluminum, iron, and silicon appears to be the major process that controls the net release of boron from fly ash when the ash is leached at loading rates of greater than 25 g of ash/L. Coprecipitation of borate species with the hydrous oxides also contributes to the retention.

Ash Composition Influence on Fusibility of Coal Ash
Applied Mechanics and Materials, 2013The coal of Zichang was selected as the sample coal, the physical properties of the ash is analyzed with ICP-AES. The ash fusion temperature was researched by adding different basic oxide contents. The results show that the general trend is decrease firstly, and then increase when adding basic oxides.

Acid leaching of coal and coal-ashes⋆
Fuel, 2003Twelve Turkish lignites and the corresponding ashes were leached in sulfuric acid (pH 1.0, 25 8C) for 14 days. Asphaltite from Silopi amended the coals. The conditions mimic treatment in the effluent from bioleaching of sulfidic mineral concentrates, but the results are equally valid for an isolated leaching process.
