A novel solvent extraction scheme was developed for the processing of Co-rich lithium-ion battery (LIB) leachate to a Ni–Co–Mn (NCM) sulfate mixture that can be directly used in precursor synthesis LIB cathodes. Conventional hydrometallurgical recycling spent LIBs usually aims at separation Li, Ni, Co, and Mn into pure fractions, which is simplified here. Operating pH number stages each were ev...

Stainless steel has a variety of applications nowadays because its mechanical strength and corrosion resistance. The large-scale machinery made up stainless an outstanding performance endurance for manufacturing industries. However, scraps accumulate with lubricant to form sludge during the operation. To reduce environmental hazards caused by sludge, this research attempts construct hydrometall...

With the development trend and technological progress of lithium batteries, battery market is booming, which means that consumption demand for batteries has increased significantly, and, therefore, a large number discarded will be generated accordingly. Solvent extraction promising approach because it simple. low in time easy to industrialize. This paper focused on selective recovery cobalt (Co...

The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP-150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex 272.Chemorex CP-150 demonstrated an effective and selective extr...

Selective separation of rare earth elements (REEs) from solutions mixed heavy and light metals by solid adsorbents is an important challenge in the fields water treatment metal recovery. The main instability many adsorbents, specifically metal–organic frameworks (MOFs), their low selectivity. Grafting particular organophosphorus compounds (OPCs) on MIL-101(Cr) MOF can provide both stability Whe...

The extraction of Terbium (III)from aqueous nitrate solutions with a supported liquid membrane was investigated using a mixture of di-(2-ethylhexyl phosphoric acid (D2EHPA) and tri-octyl phosphine oxide (TOPO) with a molar ratio 1/0.4. The Hydrophobic Polyvinylidene Fluoride (PVDF) membrane was used as solid support. The sorption process followed pseudo-second-o...
