Direct and Indirect Bio-Leaching of Co and Ni from an Iron-Rich Laterite Ore using Delftia Acidovorans and Acidithiobacillus Ferrooxidans

M. Hosseini Nasab; M. Noaparast; H. Abdollahi

Volume 12, Issue 2 , April 2021, , Pages 471-489

https://doi.org/10.22044/jme.2021.10528.2002

Abstract
  In this research work, the bio-leaching of Co and Ni from an iron-rich laterite ore is assessed using the acidophilic heterotrophic (Delftia acidovorans)and autotrophic (Acidithiobacillus ferrooxidans) bacteria. The metabolic products of the acidophilic bacteria play an important role in bio-leaching. ...  Read More

Volume 12, Issue 1 , January 2021, , Pages 235-251

https://doi.org/10.22044/jme.2021.10256.1965

Abstract
  The precipitation of aluminum hydroxide from a supersaturated sodium aluminate solution is known as an essential production step in the Bayer process. In this work, the real precipitation process in the Iran Alumina Plant was modeled by the historical data with the help of Design Expert. According to ...  Read More

Dissolution of Nickel and Cobalt from Iron-Rich Laterite Ores Using Different Organic Acids

M. Hosseini Nasab; M. Noaparast; H. Abdollahi

Volume 11, Issue 3 , July 2020, , Pages 779-797

https://doi.org/10.22044/jme.2020.9564.1869

Abstract
  Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel ...  Read More

A.H. Rezaei; H. Abdollahi; M. Gharabaghi; A. A. Mohammadzadeh

Volume 11, Issue 1 , January 2020, , Pages 119-141

https://doi.org/10.22044/jme.2019.8692.1753

Abstract
  In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in ...  Read More

Solvent extraction and stripping of zinc from synthetic chloride solution in presence of manganese and cadmium as impurities

H. Jafari; H. Abdollahi; M. Gharabaghi; A.A. Balesini

Volume 10, Issue 4 , October 2019, , Pages 1083-1093

https://doi.org/10.22044/jme.2019.8708.1755

Abstract
  In this research work, solvent extraction and stripping of zinc ions from a Zn-Mn-Cd-bearing solution was investigated using D2EHPA as the extractant in a chloride medium. The efficiency of the extraction and stripping stages was evaluated separately, and different parameters such as the pH, extractant ...  Read More

Mineral Processing
Stage specialization for design and analysis of flotation circuits

V. Radmehr; Seyed Z. Shafaei; M. Noaparast; H. Abdollahi

Volume 10, Issue 1 , January 2019, , Pages 37-47

https://doi.org/10.22044/jme.2018.6794.1504

Abstract
  This paper presents a new approach for flotation circuit design. Initially, it was proven numerically and analytically that in order to achieve the highest recovery in different circuit configurations, the best equipment must be placed at the beginning stage of the flotation circuits. The size of the ...  Read More

A comparative study of two-stage flotation of Zn and Pb oxide minerals using anionic, cationic, and mixed (cationic/anionic) collectors

M. Salehfard; M. Noaparast; Seyed Z. Shafaei; H. Abdollahi

Volume 9, Issue 4 , October 2018, , Pages 1019-1033

https://doi.org/10.22044/jme.2018.6760.1498

Abstract
  A lead-zinc carbonate ore sample containing 2.5% Pb and 9.39% Zn was used in this research work. The sample was prepared from the Darreh-Zanjir mine located in the Yazd province (Iran). Influences of the influential factors on flotation of smithsonite and cerussite were investigated. Among the different ...  Read More
