Iron oxide nanoparticles (IONPs) are characterized by superior magnetic properties, high
surface area to volume ratio, and active surface functional groups. These properties aid in …

This review mainly introduces the recycling technology of lithium and iron from spent lithium
iron phosphate (LiFePO4) batteries based on hydrometallurgy. Most of the …

The separation of rare-earth elements (REEs) is considered one of the most challenging
processes in solvent extraction. In recent years, non-aqueous solvent extraction, a unit …

As the oxygen evolution reaction (OER) imposes a high energy barrier during
electrochemical water splitting, designing highly efficient, stable, and cost-effective …

Iron can not be recovered at high value because only rare earth elements are effectively
recovered from NdFeB waste via oxidation roasting-hydrochloric acid leaching process. In …

In this manuscript, we demonstrate a room temperature electrochemical process for
efficiently recycling NdFeB magnet waste. First, the magnet waste was completely leached …

Abstract The spent Neodymium-Iron–Boron (NdFeB) magnet is potential secondary
resource of rare earth elements. Conventional hydrometallurgical processing of spent …

The disposal of spent pickle liquor from the hot-dip galvanizing process is of serious
environmental concern that demands development of safe and economical methods. The …

Copper and zinc were recovered from spent chloride brass pickle liquor using solvent
extraction and precipitation-stripping. Speciation diagrams reveal that bivalent copper and …

Zinc (Zn)-based biodegradable metals have been widely investigated for cardiovascular
stent and orthopedic applications. However, the effect of Zn surface features on adverse …
