Recovery of cobalt sulfate from spent lithium ion batteries by reductive leaching and solvent extraction with Cyanex-272
Cobalt sulfate was recovered from crushed and screened prismatic type spent lithium ion batteries (LIBs) containing 5~20 % Co, 5~7 % Li, 5~10 % Ni, 15% organic chemicals, and 7% plastics together with Cu, Al, Fe, and Mn. Cobalt was reductively leached from the -16 mesh fraction in 1 h by stirring with 2 M H2SO4 and 6 vol% H2O2, at 60 C and 300 rpm using a solid/liquid ratio of 100 g/L to give a...
متن کاملLiquid-liquid extraction of tetravalent zirconium from acidic chloride solutions using Cyanex 272.
The liquid-liquid extraction of zirconium(IV) from acidic chloride solutions was carried out with Cyanex 272 as an extractant diluted in kerosene. An increase of the acid concentration decreased the percentage extraction of metal, which indicates that the extraction follows ion exchange-type mechanism: MO2+(aq) + 2(HA)2(org) <--> MO (HA2)2(org) + 2H+(aq), where, M = Zr(IV); HA = Cyanex 272. The...
متن کاملSYNERGISTIC SOLVENT EXTRACTION OF Co(II) AND Li(I) FROM AQUEOUS CHLORIDE SOLUTIONS WITH MIXTURE OF CYANEX 272 AND TBP
In this work, separation of cobalt(II) over lithium(I) ions from aqueous chloride solutions by synergistic solvent extraction (SX) has been studied. A synergistic mixture of commercial extractants such as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) and tributyl phosphate (TBP) in kerosene was used as a selective extractant. The investigations were first performed to select optimal co...
متن کاملExtraction of Zn, Mn and Co from Zn-Mn-Co-Cd-Ni containing solution using D2EHPA, CYANEX® 272 and CYANEX® 302
Effects of pH, D2EHPA, Cyanex® 302 and Cyanex® 272 on extractions of zinc, manganese and cobalt from a Zn-Mn-Co-Cd-Ni containing solution was comprehensively investigated at the room temperature. The addition of Cyanex® 302 indicated a left-shifting-effect on the extraction curve of zinc, a right-shifting-effect on the extraction curve of manganese and no effect on the extraction of cobalt. The...
متن کاملSeparation of Nickel and Zinc Ions in a Synthetic Acidic Solution by Solvent Extraction Using D2ehpa and Cyanex 272
Solvent extraction was used to recover nickel and zinc from synthetic acidic solution. Many leaching solution and waste waters contain both zinc and nickel at the same time. Bis (2,4,4trimethylpentyl) phosphinic acid (Cyanex 272) and Di(2-ethylhexyl) phosphoric acid (D2EHPA) were used to separate nickel and zinc. In the D2EHPA system, at equilibrium pH of 2, zinc extraction was more than 98% wh...
