Investigation of Mechanism of Adsorption of Xanthate and Hydroxamate on Malachite

M. Mohammadkhani; M. Abdollahy; M. R. Khalesi

Volume 11, Issue 3 , July 2020, , Pages 921-933


  Copper oxide minerals such as malachite do not respond well to the traditional copper sulfide collectors, and require alternative flotation schemes. In many copper ore mines, significant copper oxide minerals, especially malachite, are associated with sulfide minerals. Considering that xanthates are ...  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

An insight into effect of surface functional groups on reactivity of Sphalerite (110) surface with Xanthate collector: a DFT study

M. Mohseni; M. Abdollahy; R. Poursalehi; M. R. Khalesi

Volume 9, Issue 2 , April 2018, , Pages 431-439


  The reactivity of the protonated and hydroxylated sphalerite (1 1 0) surface with xanthate was simulated using the density functional theory (DFT). The difference between the energy of the lowest unoccupied molecular orbital of the sphalerite surface and the energy of the highest occupied molecular orbital ...  Read More

Interactional effects of bubble size, particle size, and collector dosage on bubble loading in column flotation

A. Eskanlou; M. R. Khalesi; M. Abdollahy; M. Hemmati Chegeni

Volume 9, Issue 1 , January 2018, , Pages 107-116


  The success of flotation operation depends upon the thriving interactions of chemical and physical variables. In this work, the effects of particle size, bubble size, and collector dosage on the bubble loading in a continuous flotation column were investigated. In other words, this work was mainly concerned ...  Read More

Prediction of effect of fine particle removal on efficiency of a spiral circuit by size-by-size partition curves

F. Basirifar; M.R. Khalesi; M. Ramezanizadeh; M. Abdollahy; A. Hajizadeh

Volume 8, Issue 4 , October 2017, , Pages 567-571


  Partition curves are widely used to determine the spiral separator efficiency. In this work, the partition curves were used in order to investigate the particle transportation to concentrate and tailing streams. Simulation of fine particle removal using the size-by-size partition curves showed that the ...  Read More
