Role of Glycine in Cyanidation of Copper Bearing Gold Ores: an Experimental and Molecular Modeling Study

Aghil Haghdadi; Sima Mohammadnejad

Volume 14, Issue 3 , July 2023, , Pages 999-1009

https://doi.org/10.22044/jme.2023.13027.2363

Abstract
  The presence of copper bearing minerals in cyanidation of gold ores may lead to several challenges in the CIP/CIL circuits. Many solutions have been proposed to address these problems, one being the use of glycine in the cyanidation process. Here, the experimental as well as molecular modelling studies ...  Read More

Role of Functional Groups in Selective Adsorption of Gold over Copper Cyano complexes by Activated Carbon: A DFT Study

Sina Ghasemi; Sima Mohammadnejad; Mohammad Reza Khalesi

Volume 13, Issue 3 , July 2022, , Pages 891-901

https://doi.org/10.22044/jme.2022.12125.2210

Abstract
  The adsorption of gold and copper cyanide complexes on the activated carbon is investigated using the Density Functional Theory (DFT). In order to represent the activated carbon, two fullerene-like model (presenting structural defect sites) and a simple graphene layer containing different functional ...  Read More

Mechanism of Zinc Complexation by Alkaline Ligands: A Molecular Modelling Study

D. Alavi; S. Mohammadnejad; Seyed M. J. Koleini

Volume 13, Issue 2 , April 2022, , Pages 421-430

https://doi.org/10.22044/jme.2022.11417.2123

Abstract
  In this work, the mechanism of zinc hydroxide and ammine complexation in caustic and ammonia leaching is investigated by molecular modelling using the density functional theory method. The speciation of zinc complexes is defined based on the thermodynamic data and Pourbiax diagrams. The mechanism of ...  Read More

The Effect of Operating Parameters on Bromine Extraction from Desalination Plant Discharge

A. Moeini; S. Mohammadnejad

Volume 13, Issue 1 , January 2022, , Pages 165-174

https://doi.org/10.22044/jme.2022.11416.2122

Abstract
  A comprehensive utilization of concentrated seawater is crucial in order to promote the development of the desalination industry as a key solution to global freshwater. Debromination of the desalination plant effluent as well as the bromine product extraction are two parallel goals, which have been the ...  Read More
