Focusing on the comprehensive utilization of unconventional resources containing aluminum, silicon and gallium, a novel green metallurgy two-stage process for the symbiotic resources is put up including production of boehmite by liquid carbonization crystallization from sodium aluminate solutions firstly, and then electrolysis of the carbonation decomposed spent liquor to recycle the carbon alkali and extract gallium at the same time. The new process realizes the collaboration of deep rapid decomposition of sodium aluminate solution and the coordinated utilization of multi metals. With the research of ion membrane electrolysis and kinetics of the electrode process, the selectivity mechanism of the electrode reaction is studied. The coupling regulation of the electrolytic process of the spent-liquor multicomponent system and the regulate mechanism of efficient conversion of sodium bicarbonate and extraction of gallium are analyzed. In order to get the compete crystallization characteristic of boehmite, the liquid/solid composition and structure transformation of the product from the sodium aluminate solution decomposition process is studied at high decomposition rate by the crystal growth online microscopic characterization techniques and structure actuarial.The agglomeration and growth behavior of the boehmite during the multiple sodium aluminate and sodium bicarbonate solution liquid-liquid carbonation decomposed process is studied by a continuous carbonation decomposed simulation experiment to obtain optimizing conditions for the boehmite product. The electrolytic strengthened process of the traditional decomposition of sodium aluminate solution can be realized by researching the coupling and matching regulation of the subprocesses.
