The present paper reports the application oriented processes that have been developed for the recovery of rare metals (Li, Co, In), rare earth metals (Nd, Ce, La, Y, Eu), precious (Au, Ag, Pt and Pd), and non-ferrous metals (Cu, Ni, Al, Pb, Sn) from various urban ores (UR). The resources (UR) considered for processing include WEEEs, spent LCD/batteries/ magnets/ fluorescent tubes, etc. Initially, the WEEE and other wastes were classified, dismantled and pre-treated to separate plastics, epoxy, ceramics, rubber, iron cover and metallic concentrates. While non-metallics and cover could be pyrolysed/ recycled separately, the obtained metallic concentrates with enriched metal contents were processed using the hydrometallurgical techniques such as; leaching, precipitation, solvent extraction, ion-exchange, electro-winning for maximum recovery of the metals. Best methodologies followed for various flow-sheets development ensuring the high/optimum extraction and recovery of rare metals, have been discussed with the processing to strictly comply with the environmental regulations.
