查询词典 primary

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.

主要步骤包括：向铝酸钠母液中通入CO 2 进行碳分分解，一次碳酸化实现铝镓的初次分离；过滤出氢氧化钠，滤液进行二次碳酸化获得镓铝复盐沉淀，过滤后滤液经浓缩蒸发获得碳酸钠晶体，铝镓复盐沉淀溶解在偏铝酸钠母液中，重复上述过程直至铝镓复盐中的镓铝比例大于1/340，将其加入到NaOH溶液中，电解可获得纯度＞99.9％的金属镓，达到3N级水平同时在分步碳酸化的过程中获得氢氧化铝和碳酸钠副产品。
