The extraction of light rare earths (Pr and Nd) from chloride medium was investigated using a mixture di(2-ethylhexyl) phosphoric acid (P204) bis(2,4,4-trimethylpentyl) phosphinic (Cyanex272) in sulfonated kerosene. P204+Cyanex272 system exerted synergistic effect on the separation earths, coefficient higher than when P204 Cyanex272 were used as extractants alone. Pr Nd reached 1.75 pH aqueous ...

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, neodymium, and dyspersym from a nitric acid solution. The results obtained showed that ...

With the development trend and technological progress of lithium batteries, battery market is booming, which means that consumption demand for batteries has increased significantly, and, therefore, a large number discarded will be generated accordingly. Solvent extraction promising approach because it simple. low in time easy to industrialize. This paper focused on selective recovery cobalt (Co...
