Aug 01, 2008 the beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with na 2 co 3 and pas at ph about 9–10, but it is sensitive to the content of kaolinite. for the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the al 2 o 3 recovery of 87.0 and al 2 o 3 /sio 2 ratio of 8.9.
Bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant. in some cases, ore is upgraded by beneficiation washing, size classification, liquid/solid separation to remove unwanted materials such as clay and silica. at the alumina plant the bauxite ore is.
In this study, extraction of aluminum-, iron-, and titanium-bearing constituents from diaspore-type bauxite ores was investigated by stepwise treatment consisting of pre-desilication via alkali-leaching of bauxite ore, extraction of alumina via bayer process, and recovery of iron from red mud via magnetic separation. the pre-desilication results showed that the removal of silica reached 73.92 mining.
