Comparative leaching experiments for trace elements in raw coal, laboratory ash, fly ash and bottom ash
International Journal of Coal Geology 40 (1999) 103-108，-0001，（）：
obtained by ashing of the coal under 850℃. Comparative-leaching experiments were carried out on each fraction under various pH conditions. A mathematical model for leaching of trace elements has been developed and leaching intensity (I1) has been calculated for each element. The results show that pH of the solution, leaching time, and particularly, properties and occurrence of the elements, have a strong influence on leaching behavior.
