Modelling and optimization of digestion efficiency of bauxite in Bayer process: Iran Alumina company

M. R. Khani; M. Karamoozian

Volume 10, Issue 3 , July 2019, , Pages 799-809


  In the present work, we investigated and optimized the digestion efficiency, A/S (Al2O3/SiO2 in red mud), and N/S (Na2O/SiO2 in red mud) of mixed bauxite in Iran Alumina Company using the Bayer process. Digestion experiments were carried out in an induction rotary autoclave on a mix of Jajarm, Yazd, ...  Read More

Gallium extraction from Jajarm Bayer process liquor using micro-emulsions

H. Amani; H. Naderi

Volume 8, Issue 2 , April 2017, , Pages 269-276


  Gallium extraction from Jajarm Bayer process liquor (Jajarm, Iran) was investigated using microemulsions. Also the behavior of aluminum was studied as an impurity. Kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, ...  Read More

Volume 8, Issue 1 , January 2017, , Pages 75-81


  Low grade diasporic bauxite in the Jajarm mine with an A/S (Al2O3/SiO2) ratio of 2.3 is not usable in the Bayer process at Jajarm Alumina Complex. Due to the severe interlocking effect between the diaspore and aluminosilicate minerals (Chamosite and Kaolinite) and iron-containing minerals in a microcrystal ...  Read More
