The main steps include as follows: CO2 is led into the mother liquor of sodium meta-aluminate to carry out carbon content decomposing; the primary separation between the aluminum and the gallium is realized by primary carbonatation to filter out sodium hydroxide; secondary carbonatation is carried out on the filtrate to obtain the deposit of the complex salt of gallium and aluminum; a sodium carbonate crystal is obtained after the filtered filtrate is condensed and vaporized; the deposit of the complex salt of gallium and aluminum is dissolved in the mother liquor of sodium meta-aluminate; the processes are repeated until the proportion of gallium and aluminum in the complex salt of gallium and aluminum is larger than 1/340; then the complex salt of gallium and aluminum is added into the NaOH liquor and electrolyzed, thus obtaining the metal gallium with a purity larger than 99.9 percent which reaches the level of 3; simultaneously, the byproducts of the aluminum hydroxide and the sodium carbonate during the process of carbonatation by steps are obtained.
