Ammonium sulfate ((nh4) 2so4) as the activator for roasting, can be inert fly ash in al into the activity of soluble out of aluminum, with roasting - leaching process extracted from coal ash Al2O3. Under certain conditions (nh4) 2so4 mixed with fly ash roasting, selection of h2so4 active aluminum sa

Based on ammonium sulfate (4) 2 (NH SO 4) as a surfactant for roasting, you can be lazy in the pulverized fuel ash Al changes of survival of the soluble salts of aluminum, a burning-leaching process extracted from coal ash O Al 2 3. Under certain conditions (4) 2 NH SO 4 coal ash mixed with burning,

When based on ammonium sulfate ((NH4)2SO4) achievement for roasting activator, may inert Al transform the aluminum salt the pulverized coal ash in which active easy to dissolve, uses the roasting - leaching craft to withdraw Al2O3 from the pulverized coal ash.Under the controlled condition (NH4)2SO4

Based on ammonium sulfate ((NH4) 2SO4) as to when the firing activator, can transform the inert Al from fly ash of survival of soluble aluminum salts, roasting-leaching process from fly ash used in extraction of Al2O3. Under certain conditions, (NH4) 2SO4 is mixed with fly ash roasting, selection of
