【Abstract】 A study was made of the alkali recovery from sodium hydrate alumino silicate by wet treatment. The influences of temperature, L/S ratio, time and lime dosage on alkali recovery were investigated respectively, and the proper technical conditions are proposed. The experimental results indicated that the alkali recovery increased with the increase of temperature, whearas there was no obvious effect of time and L/S ratio on the alkali recovery. The alkali recovery could be improved by increasing the lime dosage.更多还原
