characteristics of the bauxite in Wuchuan-Zheng’an-Daozhen area were investigated through the handle specimen observation, thin section analysis, XRD and SEM. The mineral analyses reveal that diaspore..., 1968, 3(4): 368-374. [42] Nia R. Genesis of boehmite and diaspore in greek upper cretaceous bauxites of the parnassos-kiona zone proc[C]// Nia R.

decreased sharply from digestion of boehmite or diaspore to seed precipitation, about 95% lithium was precipitated into red mud (bauxite residue) and aluminum hydroxide. This study provides a valuable... of boehmite and diaspore by Bayer process. 3.1.1 Effect of reaction time The equilibrium concentration of lithium in sodium aluminate solution is closely related to the dissolution rate of lithium......

of dissolution process show that the kaolinite is symbiotic with diaspore but without cladding. The dissolution ratio of kaolinite is close to 100% at 100 °C for 90 min. The dissolution kinetic equation is 1-(1-α... the atmospheric pressure, kaolinite can be dissolved by alkali solution, yet the diaspore cannot be dissolved so that the purpose of improving the A/S of concentrate can be achieved with very simple......
