Thermal Processing of Jarosite Leach Residue for a Safe Disposable Slag and Valuable Metals Recovery
Metals, 2018 In electrolytic production of zinc, the iron levels in the solutions are controlled by precipitation of jarosite or goethite. These precipitates also co-precipitate unrecovered valuable metals (Zn, Pb, Cu, Ag) as well as elements of concern (As, Cd, Hg).

Batteries &Supercaps, Volume 9, Issue 8, August 2026.The first step of the direct recycling process of lithium‐ion battery (LIB) cathodes is investigated through shear milling of NMC622 materials. An excessive milling energy could alter particle size and induce crystalline microstrains, leading to electrochemical performance loss.
