“…Acidic extractants are frequently used for the separation of these metals but both the extraction efficiency and the selectivity are highly dependent on the aqueous phase pH. Moreover, the selectivity is often not high enough and several synergistic systems have been developed to obtain a satisfying selectivity (Joo et al, 2016b); (Joo et al, 2015a).…”

“…In particular, a mixture of extractants has been employed for the separation and purification of Co and Mn [14][15][16][17][18]. Based on the reported studies, many researchers have been interested in the individual separation of Co and Mn for applications in a field that is different from the final product.…”

Abstract:We investigated the preparation of CMB (cobalt-manganese-bromide) and CMA (cobaltmanganese-acetate) liquid catalysts as petroleum liquid catalysts by simultaneously recovering Co and Mn from spent Li-ion battery cathode material. To prepare the liquid catalysts, the total preparation process for the liquid catalysts consisted of physical pre-treatments, such as grinding and sieving, and chemical processes, such as leaching, solvent extraction, and stripping. In the physical pre-treatment process, over 99% of Al was removed from material with a size of less than 0.42 mm. In the chemical process, the leaching solution as obtained under the following conditions: 2 mol/L sulfuric acid, 10 vol % H 2 O 2 , 0.1 of solid/liquid ratio, and 60 • C. In the solvent extraction process, the optimum concentration of bis (2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272), the equilibrium pH, the degree of saponification, the organic phase/aqueous phase ratio isotherm, and the stripping study for the extraction of Co and Mn were investigated. As a result, Co and Mn were recovered by 0.85 M Cyanex 272 with 50% saponification in counter current two extraction stages. Finally, a CMB and CMA liquid catalyst containing 33.1 g/L Co, 29.8 g/L Mn, and 168 g/L Br and 12.67 g/L Co, 12.0 g/L Mn, and 511 g/L C 2 H 3 O 2 , respectively, was produced by 2 M hydrogen bromide and 50 vol % acetic acid; it was also found that a shortage in the concentration can be compensated with cobalt and manganese salts.

“…Depending on the affinity of the extractant for the target metal, a good efficiency and selectivity could be obtained, even with low concentrations of metals in the aqueous phase and advantageously with a low concentration of extractant in the organic phase. The recovery of lithium from the cathodes of spent lithiumion batteries using solvent extraction has been the object of a few studies [15][16]. Most of the investigations have focused on the extraction of cobalt, the most critical element in lithium-ion batteries [17][18].…”

Solvent extraction of lithium ions from sulfuric acid solutions was investigated using imidazolium-based ionic liquids as diluents and tri-n-butyl phosphate as specific ligand. Aqueous phases used were simulating leach liquors of spent lithium-ion batteries, with lithium, cobalt and nickel ions in acidic solutions. A low acidity and a large amount of extractant can ensure high extraction efficiency. But the better selectivity for the lithium ions over the transition metals is obtained using a low amount of extractant and a low pH (pH<3). The extraction of the lithium ions occurs by cation exchange with the ionic liquid cations. A sacrificial cation was introduced in the organic phase to prevent the losses, but the cation exchange is only reduced by 20 %. The increase of the ionic liquid cation alkyl chain length can presumably suppress the cation exchange mechanism, reducing substantially the losses. But the addition of a lipophilic counter-anion in the organic phase is needed to ensure a mechanism of ion pairing with the lithium ion in the organic phase. Using the 1-decyl 3methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid associated to tri-butyl phosphate, a satisfying extraction efficiency is obtained for the lithium ion, together with a sufficient selectivity among the transition metal ions.
