Recovery of cobalt sulfate from spent lithium ion batteries by reductive leaching and solvent extraction with Cyanex 272
TL;DR: 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 as mentioned in this paper.
Journal ArticleDOI

TL;DR: Co recovery via the ammoniacal leaching is believed to gain a competitive edge on convenitonal acid leaching both by reducing the sodium hydroxide expense for increasing the pH of leaching solution and by removing the separation steps of Mn and Al.
Journal ArticleDOI
Preparation of cobalt oxide from concentrated cathode material of spent lithium ion batteries by hydrometallurgical method
TL;DR: Cobalt oxide was prepared from spent lithium ion batteries (LIBs) by reductive leaching, copper sulfide precipitation, cobalt oxalate precipitation and thermal decomposition as mentioned in this paper.
Journal ArticleDOI
Separation of zinc from spent zinc-carbon batteries by selective leaching with sodium hydroxide
TL;DR: Physical methods such as crushing and sieving followed by magnetic separation steps were applied to separate nonmagnetic material (88.4 Wt%) from zinc-carbon spent batteries as discussed by the authors.
