TL;DR: In this paper, a comprehensive review of the resources of lithium and status of different processes/technologies in vogue or being developed for extracting lithium and associated metals from both primary and secondary resources are summarized.

TL;DR: In this paper, the conditions for the dissolution of valuable metals were optimized while varying the parameters such as acid concentration, leaching time, temperature and pulp density, and it was found that with 1M H2SO4 and 0.075 M NaHSO3 as reducing agent ∼96.7% Li, 91.6% Co, 96.4% Ni and 87.9% Mn were recovered in 4h at 368 K and a pulp density of 20 g/L.

TL;DR: The mode of leaching of the metals from the spent LIBs was further examined by chemical analysis of the samples at various stage of processing which was further corroborated by characterizing the untreated sample and the leach residues by XRD phase identification and the SEM-EDS studies.

TL;DR: Kinetic data for the dissolution of all the rare earth metals showed the best fit to the chemical control shrinking core model and the leaching of metals followed the mechanism involving the chemical reaction proceeding on the surface of particles by the lixiviant.

TL;DR: In this paper, the extraction of chromium(III) from a model solution and from a tannery waste solution was studied by ion exchange using Indion 790 resin which is a macro-porous strongly acidic cation exchange resin of sulfonated polystyrene group.
