摘要
The present invention is a method for recovering a pure aluminate (III) solution from which silicon elements, which are easily mixed as impurities, have been removed from black dross through wet extraction, and a method for synthesizing magnesium aluminate spinel oxide using this aluminate solution it's about how to The method according to the present invention includes a mechanical activation step of activating the black dross by applying mechanical energy; a leaching step of dissolving alumina and silica components contained in the activated black dross using an alkali solution to prepare a leaching solution; and a purification step of precipitating and removing the silica component from the leaching solution.
