  • Coal fly ash as a resource for rare earth elements

    24.01.2015 · As ash is derived from the inorganic minerals in the coal such as quartz feldspars clays and metal oxides the major elemental composition of coal ash is similar to the composition of a wide variety of rocks in the Earth s upper crust (EPRI 2009). Therefore oxides of silicon aluminium iron and calcium contain more than 90 of the mineral component of typical coal fly ash. Minor elements
