Cyanide Removal from Tailing Slurry of Gold Processing Plant using Surfactant-modified Zeolite

Mehdi Soleymani Gharegol; Kazem Badv; Behzad Nemati akhgar

Volume 15, Issue 1 , January 2024, , Pages 285-300


  This paper carried out the study on removing cyanide from aqueous solutions by modified zeolite with hexadecyltrimethylammonium bromide. After determining the properties of the prepared adsorbent by the XRD, SEM, FTIR, and BET techniques, the effect of parameters such as the initial concentration of ...  Read More

Adsorptive Study of Cadmium Removal from Aqueous Solution Using a Coal Waste Loaded with Fe3O4 Nanoparticles

S. Mirshrkari; V. Shojaei; H. Khoshdast

Volume 13, Issue 2 , April 2022, , Pages 527-545


  A coal waste sample loaded with Fe3O4 nanoparticles is employed as an efficient adsorbent to remove Cd from synthetic wastewater. The synthesized nanocomposite is characterized using the Fourier transform-infrared (FT-IR), X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques. ...  Read More

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


  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

Leaching of gold ores with high cyanicides: a physico-chemical modeling approach

Y. Kianinia; M. R. Khalesi; M. Abdollahy; A. Khodadadi Darban

Volume 10, Issue 1 , January 2019, , Pages 87-94


  Processing of gold ores with high sulfide minerals is problematic as they consume cyanide and reduce gold leaching. Optimization of gold leaching and cyanide consumption requires a methodology to estimate the amount of exposed cyanicides, their leaching kinetics, and speciation of cyanide complexes that ...  Read More
