sintering process bauxite

Mar 11, 2019· A lime sintering process for production of alumina from boehmite and diaspore bauxites was developed for producing alumina from low grade bauxite in China and Russia. The process involves a pyro-metallurgical sinter approach, which produces aluminum while "locking up" the silica as clinker, thus preventing it from contaminating the alumina.

Sintering Of Bauxite

The heating change of bauxite is divided into three stages: decomposition stage, secondary mulliteization stage and recrystallization stage. Decomposition stage: In this stage, the diaspore and kaolinite in the bauxite begin to be dehydrated at 400 degrees Celsius, and the reaction is violent at 450 to 600 degrees Celsius, and the reaction is completed at 700 to 800 degrees Celsius.

Sintering process of diasporic bauxite with high iron content at low ratio of lime to silica for alumina production …

The sintering process of diasporic bauxite with high iron content was studied. The results show that 3CaO·2SiO2, and 2CaO·SiO2, are primarily formed in the sintering process when diasporic bauxite is sintered at soda ratio Na2O/(Al2O3+Fe2O3) of 1 and lime ratio CaO/SiO2 of 1.5. The increase of n(CaO)/n(SiO2) decreases the extraction of alumina and silica. The prolongation of sintering time ...
