Study on the recovery of platinum group metals from the catalyst leaching residue by iron collection method
Research on the recovery of platinum group metals by iron capture method from oxidation leaching residue of automotive catalysts.Key research focuses on the effects of trapping agents,reducing agents,fluxes,reaction temperature,and reaction time on the capture efficiency of platinum group metals.The recovery rates are 97.19%、92.88%and for Pt,Pd and Rh,respectively,when the collection condition is as follows:Under the conditions of 20%capture agent ratio,12%reducing agent ratio,25%flux ratio,calcination temperature of 1 400℃,and constant temperature reaction time of 4 hours.
