拜耳法最关键的工序是铝土矿的溶出,此时生成了铝酸钠真溶液: Al(OH)_3+NaOH(?)Na~++(Al(OH)_4)~- Al(OH)_3+2NaOH(?)2Na~++(Al(OH)_5)~(2-) Al(OH)_3+3NaOH(?)3Na~++(Al(OH)_6)~(3-) 该反应为平衡反应,溶解的氧化铝不仅以简单的
The most important process in the Bayer process is the dissolution of bauxite. At this time, a true solution of sodium aluminate is generated: Al (OH) 3 + NaOH Na ~ ++ Al ~ OH ~ _3 + 2NaOH () 2Na ~ ++ (Al (OH) _5) ~ (2-) Al (OH) _3 + 3NaOH (?) 3Na ~ To balance the reaction, dissolved alumina is not only simple
