Two alternative process routes for recovering pure indium from waste liquid crystal display panels
Recovering indium from liquid crystal display (LCD) screen waste is important from a sustainability point of view for several reasons: the environmentally hazardous metals are not landfilled, the recovery process involves ...
Recovering rare earth elements from phosphogypsum using a resin-in-leach process: Selection of resin, leaching agent, and eluent
Phosphogypsum (PG) is an attractive secondary raw material for rare earth elements (REEs) because it is abundant and contains significant amounts of REEs. Herein, the resin-in-leach (RIL) process for REE recovery from PG ...
Novel mechanical pre-treatment methods for effective indium recovery from end-of-life liquid-crystal display panels
This study investigated the suitability of mechanical pre-treatment methods (mechanical abrasion and treatments of heat, laser, and plasma) together with a hydrometallurgical process comprising leaching and cementation for ...
Removal and recovery of arsenic from concentrated sulfuric acid by solvent extraction
Arsenic-contaminated sulfuric acid solutions are produced in large quantities as by-product during pyrometallurgical processing of sulfide minerals. Options for re-using such acid solutions are increased if the arsenic is ...
Numerical simulation of counter-current liquid–liquid extraction for recovering Co, Ni and Li from lithium-ion battery leachates of varying composition
Fractionation of Li-ion battery waste leachates into high-purity Li, Ni, and Co streams in a liquid−liquid extraction circuit was studied using numerical simulations. A new mechanistic mathematical model explaining the ...
