Abstract
PURPOSE: In extracting an alkali metal from slag, to enable simultaneous treatments of extraction of alkali metal and removal of impurities, by adding a combustion product of dolomite, combustion product of dolomit limestone or their hydoxide to an extraction tank.
CONSTITUTION: The extraction device 1 is charged with the slag a, the extracted solution b consisting of water or it as a main ingredient together with the treatment c, e.g., combustion products of dolomite or dolomite limestone or their hydroxides. The carbon dixode gas d is introduced into the device 1, the pH of the solution is adjusted to about 10W12, and the temperature is made to ≥about 80°C. Na is extracted, the impure components, e.g., P, S, Si, eluted in the solution are insolubilized and reduced again into the insoluble residue. In these reactions, p is removed as shown by the formula I, S as shown by the formula II, and Si is considered to be removed by a certain chemical bond of SiO2 with Mg(OH)2.
