An experimental model for determination of the entrainment in column flotation based on operation parameters

reza zolfaghari; Mohammad Karamoozian

Articles in Press, Accepted Manuscript, Available Online from 25 August 2024

https://doi.org/10.22044/jme.2024.14620.2758

Abstract
  In flotation, entrainment (ENT) affects the recovery of the concentrate, and the entrainment model is often supposed to be only a function of particle size in models. Some research shows that other variables may also significantly affect ENT. In this study, some flotation experiments executed using a ...  Read More

Effect of Stable Nano-microbubbles on Sulfide Copper Flotation and Reduction of Chemicals Dosage

Ali Nikouei Mahani; Mohammad Karamoozian; Mohammad Jahani Chegeni; Mohammad Mahmoodi Meymand

Volume 15, Issue 1 , January 2024, , Pages 261-283

https://doi.org/10.22044/jme.2023.13205.2413

Abstract
  Generally, mineral processing plants generate a large quantity of waste in the form of fine particles. The flotation speed of mineral microbubbles by coarse bubbles is dramatically higher than that of individual particles. The advantage of microbubbles is due to the increase of binding efficiency of ...  Read More

Recovery of Iron from Bauxite Red Mud by Reduction Roasting Method

Nooshin Navi; Mohammad Karamoozian; Mohammad Reza Khani

Volume 14, Issue 4 , October 2023, , Pages 1295-1305

https://doi.org/10.22044/jme.2023.13138.2389

Abstract
  Red mud is an important solid tailing with strong alkalinity that is obtained during the extraction of alumina in the Bayer process. The global reserve of red mud is more than 4 billion tons, and its disposal as tailing has always been a serious environmental problem. This tailing is considered as a ...  Read More

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

https://doi.org/10.22044/jme.2021.11213.2101

Abstract
  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

https://doi.org/10.22044/jme.2019.8398.1720

Abstract
  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

https://doi.org/10.22044/jme.2018.6338.1457

Abstract
  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

https://doi.org/10.22044/jme.2013.143

Abstract
  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
