Enhanced Desilication of High Alumina Fly Ash by Combining Physical and Chemical Activation
In this work, a physical–chemical activation desilication process was proposed to extract silica from high alumina fly ash (HAFA). The effects of fly ash size, hydrochloric acid concentration, acid activation time, and reaction temperature on the desilication efficiency were investigated c...
