“…Moreover, the absorbance peak intensity of 1194 cm –1 assigned to the PO stretching vibration decreases, and the absorbance peak of 1021 cm –1 assigned to the P–O–C stretching vibration shifts to 1037 cm –1 . These results are attributed to the coordination of metal ions with P507 . The P–O–C group is also observed to the have the same shift in the extraction of lutetium(III) and P507.…”

“…The results are shown in Figure . For pure P507, the absorption peaks at around 2958 and 1461 cm –1 are attributed to the −CH 3 stretching vibration, and the absorption peaks at around 2928 and 2860 cm –1 are attributed to the −CH 2 – stretching vibration . The broad absorbance peaks of 2315–2319 and 1677 cm –1 attributed to the P–O–H stretching vibration in pure P507 disappear after extraction, demonstrating that metal ions (Co-III, Ni-II, and Mn-IV) replace the hydrogen atom in the P–O–H group .…”

The advancement of the electric vehicle industry has inevitably resulted in the increased production and numerous scraps of lithium-ion batteries (LIBs), among which the nickel cobalt manganese ternary material has become the fastest growing and largest proportion material in the lithium battery cathode material market. Therefore, a practical and effective method to recycle spent LIBs must be established. In this study, an efficient recycling method was proposed to leach value metals from cathode materials via the excellent solubility of deep eutectic solvents to metals, and regenerated LiNi1/3Co1/3Mn1/3O2 was prepared via coextraction and coprecipitation. 91.63% of Li, 92.52% of Co, 94.92% of Ni, and 95.47% of Mn are leached from the recycled cathode electrode. The kinetic experiments indicated that the leaching process fitted well to the shrinking core model controlled by chemical reactions. The value metals could be extracted with high efficiencies by adjusting the operating parameters in the step of coextraction. Moreover, the electrochemical tests of the regenerated ternary material revealed that the material had an excellent electrochemical performance. The proposed method, which can realize the sustainable development of spent LIBs, has great potential in the deep recycling of spent LIBs.

“…Liu et al [99] found that the addition of 15 vol.% isooctyl alcohol during the D2EHPA extraction reduces the efficiency of scandium extraction from 1 M H 2 SO 4 solution, but promotes its separation from titanium and zirconium with separation factors of 34 and 494 for Sc/Zr and Sc/Ti, respectively. Ochsenkühn-Petropulu et al [100] selectively separated scandium from yttrium and heavy lanthanides at pH = 0 by 0.05 M D2EHPA in hexane, and in the second stage extracted La and Ce by an increase in D2EHPA concentration to 1 M at pH = 1.5.…”

Extraction of Valuable Elements from Red Mud with a Focus on Using Liquid Media—A Review

et al. 2021

View full text Add to dashboard Cite

Bauxite residue, known as red mud, is a by-product of alumina production using the Bayer process. Currently, its total global storage amounts to over 4.6 billion tons, including about 600 million tons in Russia. The total global storage of red mud occupies large areas, leading to environmental damage and increasing environmental risks. Moreover, it contains a significant amount of sodium, which is easily soluble in subsoil water; therefore, a sustainable approach for comprehensive recycling of red mud is necessary. The bauxite residue contains valuable elements, such as aluminum, titanium, and scandium, which can be recovered using liquid media. In recent years, many methods of recovery of these elements from this waste have been proposed. This paper provides a critical review of hydrometallurgical, solvometallurgical, and complex methods for the recovery of valuable components from red mud, namely, aluminum, titanium, sodium, and rare and rare-earth elements. These methods include leaching using alkaline or acid solutions, ionic liquids, and biological organisms, in addition to red mud leaching solutions by extraction and sorption methods. Advantages and disadvantages of these processes in terms of their environmental impact are discussed.

Study on the adsorption–desorption behaviours of La³⁺, Sm³⁺, and Y³⁺ by HEHEHP extraction resin in chloride medium

The adsorption–desorption behaviours of La3+, Sm3+, and Y3+ on 2‐ethylhexylphosphonic acid mono‐2‐ethyl hexyl ester (HEHEHP) extraction resin were investigated in a chloride medium. The effects of reaction time, pH, hydrochloric acid concentration, flow rate, and adsorption mechanism were studied in detail using static and dynamic experimental methods. The results show that La3+ is the first to reach adsorption equilibrium, followed by Sm3+ and Y3+; the highest adsorption capacities of La3+, Sm3+, and Y3+ are obtained at solution pH of 4 and in the order of Y3+ > Sm3+ > La3+. La3+, Sm3+, and Y3+ can be eluted by 0.3, 0.5, and 3 mol/L hydrochloric acid, respectively, indicating that La3+ elutes most easily, and Y3+ is difficult. Moreover, the flow rate has little effect on the peak of rare earth desorption. The adsorption process is chemisorption; the slope method indicates that for each mol Sm3+ or Y3+ ion adsorbed, 3 mol H+ ions are simultaneously released, but two for La3+ under the given pH conditions. It is expected to provide theoretical and technical support for preparation of ultra‐high purity rare earth by HEHEHP extraction resin.
