Rare-earth and/or critical metals are one of the most valuable and neglected part of e-waste. Hydrometallurgical recovery methods of rare earth and critical metals from magnet scraps, fluorescent lamps, CRTs, LCDs, lion batteries, PV cells, and solar panels are broadly presented in this chapter. Industrial-scale recovery techniques of Nd, Pr, Dy, Sm, Co, Zr, etc. from magnet scraps; phosphors from lamps and CRTs; In from LCDs; Cd, Te, Sn, In, Ga, etc. from PV cells/solar panels; Pb, glass, and phosphor from CRTs; and Co from Lion rechargeable batteries are briefly presented in this chapter.
