Hydrometallurgical Process - an overview
Hydrometallurgical Process. Hydrometallurgical processes allow to obtain as final products base metals (Cu, Zn) and salts of critical metals like yttrium and europium oxalates with high purity that could be sent to the market or sold to companies for refining. From: Waste Electrical and Electronic Equipment Recycling, 2018. Related terms: Cobalt; Lithium

Hydrometallurgy - an overview ScienceDirect Topics
Traditional hydrometallurgical extraction processes include acid leaching to recover metals. HNO 3 /HCl/HClO 4 /H 2 SO 4 was used for extracting Cu, Pb, Zn, etc. Aqua regia (AR) was also used for nonselective and aggressive digestion of BMs (Cu, Pb, and Zn) and PMs (Ag and Au) from WEEE. Toxic cyanide leaching of Au has been used selectively for more than a century.

Hydrometallurgical processing of waste multilayer
2020-11-1 A hydrometallurgical process to recover Cu, Ag, Au and Pd selectively from PCBs of e-waste was also investigated. 99% Cu got dissolved in two consecutive stages using H 2 SO 4 as leachant along with H 2 O 2 as reductant. The leached residue obtained was treated using acidic thiourea and ferric ion as oxidizing agent to dissolve 85.76% Au and 71.36% Ag followed by their precipitation using sodium
