Decomposition of sodium aluminate solution is the key step for alumina production; however, approximately only 55% alumina yield is obtained by seeded precipitation. So, it is difficult to obtain sodium aluminate solution with high caustic ratio. In

In the novel clean chromate production process, the alkali liquor recycled to decompose the chromite ore mainly consists of KOH and K 2 CO 3 which accumulates aluminium impurity and affects the quality of the product greatly. Aluminium impurity can b
