Recovery of valuable metals from cathodic active material of spent lithium ion batteries: Leaching and kinetic aspects.
This work is focussed on the processing of cathodic active material of spent lithium ion batteries (LIBs) to ensure resource recovery and minimize environmental degradation. The sulfuric acidExpand
Bioleaching of gold and copper from waste mobile phone PCBs by using a cyanogenic bacterium
Abstract Chromobacterium violaceum (C. violaceum), a cyanide generating bacterium has been used to leach out gold and copper from the waste mobile phone printed circuit boards (PCBs) containingExpand
Hydrometallurgical processing of spent lithium ion batteries (LIBs) in the presence of a reducing agent with emphasis on kinetics of leaching
Abstract In this study, sulfuric acid leaching was applied to recover lithium, cobalt, nickel and manganese from the cathodic active material of spent LIBs in presence of a reducing agent, sodiumExpand
Recovery of lithium and cobalt from waste lithium ion batteries of mobile phone.
In view of the stringent environmental regulations, availability of limited natural resources and ever increasing need of alternative energy critical elements, an environmental eco-friendly leachingExpand
Extraction of lithium from primary and secondary sources by pre-treatment, leaching and separation: A comprehensive review
Abstract In this comprehensive review resources of lithium and status of different processes/technologies in vogue or being developed for extraction of lithium and associated metals from both primaryExpand
REMEDIATION OPTIONS FOR THE TREATMENT OF ELECTROPLATING AND LEATHER TANNING EFFLUENT CONTAINING CHROMIUM—A REVIEW
Chromium used in the electro plating and tanning industries causes environmental pollution through the generation of effluent. Various methods such as precipitation–flocculation coupled withExpand
Optimizing the thiosulfate leaching of gold from printed circuit boards of discarded mobile phone
An environmentally benign process involving thiosulfate leaching was developed in order to recover gold from the printed circuit boards (PCBs) of discarded mobile phone. The effect of concentrationExpand
Extraction of lanthanum and cerium from Indian red mud
Abstract Laboratory-scale experiments were conducted to recover lanthanum and cerium from Indian red mud in sulfuric acid medium. The method includes acid leaching of red mud pulp and subsequentExpand
A Comparative Adsorption Study of Copper on Various Industrial Solid Wastes
The adsorption behavior of Cu on three solid waste materials—sea nodule residue (SNR), fly ash (FA), and red mud (RM)—was investigated. The effects of various parameters, such as pH of the feedExpand
Recovery of chromium (VI) from electroplating effluent by solvent extraction with tri-n-butyl phosphate
Recovery of hexavalent chromium from a model and real electroplating effluent by solvent extraction with tri-n-butyl phosphate (TBP) was studied. In different acid media chromium(VΙ) extraction withExpand
