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

http://dx.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

http://dx.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

S. Nazari; Seyed Ziaedin Shafaei; M. Gharabaghi; R. Ahmadi; B. Shahbazi

Volume 9, Issue 2 , April 2018, , Pages 539-546

http://dx.doi.org/10.22044/jme.2017.6404.1461

Abstract
  In this work, the effects of the types of frother (MIBC, pine oil, and A65) and operational parameters (impeller speed and air flow rate) on the flotation of quartz coarse particles was investigated using nano bubbles (NBs). Quartz particles of the size of -425+106 mm and three types of frother were ...  Read More

Optimization of parameters affecting recovery of copper from Sarcheshmeh low-grade sulfide ore using Bioleaching

M. Naderi; Seyed Z. Shafaie; M. Karamoozian; Sh. Gharanjik

Volume 8, Issue 4 , October 2017, , Pages 523-537

http://dx.doi.org/10.22044/jme.2017.848

Abstract
  In this work, the parameters affecting the recovery of copper from the low-grade sulfide minerals of Sarcheshmeh Copper Mine were studied. A low-grade sulfide ore was used with a copper grade of 0.25%, which was about 28% of the mineral oxide, and the sulfide minerals made up the rest. Much more sulfide ...  Read More

Investigation of performances of solvents D2EHPA, Cyanex272, and their mixture system in separation of some rare earth elements from a Nitric Acid solution

Seyyed M. Seyyed Alizadeh Ganji; S. Z. Shafaie; N. Goudarzi

Volume 7, Issue 2 , July 2016, , Pages 143-148

http://dx.doi.org/10.22044/jme.2016.476

Abstract
  This work was aimed to evaluate and compare the performances of the solvents D2EHPA (Di-(2-ethylhexyl) phosphoric acid), Cyanex 272 (bis (2,4,4-trimethylpentyl) phosphinic acid), and a mixture system of D2EHPA and Cyanex272 in the separation of some rare earth elements (REEs) including lanthanum, gadolinium, ...  Read More

Effect of grinding time on flotation recovery of copper smelting slags in Bardaskan district

M. Shamsi; M. Noparast; Seyyed Z. Shafaie; M. Gharabaghi; S. Aslani

Volume 6, Issue 2 , July 2015, , Pages 237-249

http://dx.doi.org/10.22044/jme.2015.474

Abstract
  Copper smelting slags are hard materials. Therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. Copper smelting slags in the Bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree ...  Read More

Optimization of cyanidation parameters to increase the capacity of Aghdarre gold mill

Bahman Ghobadi; Mohammad Noaparast; Seid Ziaedin Shafaei; Majid Unesi

Volume 5, Issue 2 , July 2014, , Pages 121-128

http://dx.doi.org/10.22044/jme.2014.328

Abstract
  This study investigates the optimization of gold dissolution from Aghdarre ore. Therefore, a laboratory investigation was initiated, to improve the leaching conditions with the objective of maximizing mill capacity with no reduction on gold recovery. It was observed that the time reduction from 25 to ...  Read More
