An Experimental and CFD Investigation on Effect of Initial Bubble Diameter on its Rise Velocity Profile in A Laboratory-Scale Flotation Column Cell

N. Khorasanizadeh; M. Karamoozian; H. Nouri-Bidgoli

Volume 12, Issue 4 , October 2021, , Pages 1089-1102


  The bubble diameter effect on the bubble rise velocity profile in a flotation column is studied by the two-phase computational fluid dynamics (CFD) method. The simulations are done in the ANSYS® Fluent® software using a two-phase volume of fluid model. The computational domain is a square cross-section ...  Read More

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

Desulfurization of coal by HNO3 leaching: Optimization of influential factors using Box-Behnken design

S. Shahraki; M. Karamoozian; A. Azizi

Volume 9, Issue 3 , July 2018, , Pages 657-665


  Sulfur is one of the most significant impurities in coal, which reduces the quality of coal and also results in environmental pollution. This work was aimed to investigate the removal of sulfur from coal by the leaching method employing parameters expected to affect the removal rate such as acid concentration ...  Read More

Investigation on selective rhenium leaching from molybdenite roasting flue dusts

Ali Entezari; Mohammad Karamoozian; M Eskandari Nasab

Volume 4, Issue 2 , July 2013, , Pages 77-82


  The possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. The results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. On the other hand, addition of small amounts ...  Read More
