When concentration of the additive in sodium aluminate solution reach 0.175 g/L, the average size of ATH is 3.9 μm. The infrared spectra analysis show......
. And the decomposed silicon dioxide will come into the crude liquor and complicate the desilication system. It has been reported that γ-2CaO·SiO2 is inert in sodium aluminate solution, and it normally does not react... of calcium aluminate slag were studied using XRD. The results show that the decomposition rate of γ-2CaO·SiO2 increases with the increase in leaching time and sodium carbonate concentration. The main......
fine ATH, the seeded precipitation from sodium aluminate solution has a lot of advantages, such as low cost, spent-liquor circulation and less pollution. But high soda (expressed in Na2O) content..., CHALCOA) and spent liquor (from an alumina refinery in Henan province, China), and μSi (mass ratio of alumina to silica in solution) of pregnant liquor was 400±30 after desilication in sodium aluminate......
