Solvent Extraction of Zinc from a Bioleaching Solution by Modification of D2EHPA: Optimization and Thermodynamic Studies

P. Tahmasebizadeh; S. Javanshir

Volume 12, Issue 1 , January 2021, , Pages 253-269


  In this work, zinc extraction from an industrial leach solution was investigated by saponified di(2-ethylhexyl)phosphoric acid (D2EHPA). The solution obtained was from a bioleaching process of a low-grade lead-zinc sulfide ore that contained 50 g/L of zinc and 6.3 g/L of iron. The selective and high ...  Read More

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

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


  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

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


  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
