Recovery of platinum group metals from platinum group metal-containing materials
Published 2011
Patent, WO 2011/140593 A1
There is provided a process for extracting platinum group metals from a platinum group metal-containing material, in particular spent automotive catalyst. The process involves roasting said material under oxidative conditions and further roasting said material under reducing conditions, then contacting said roasted material with a chloride leaching solution in the presence of an oxidising agent to produce a leachate solution containing he platinum group metals. The platinum group metals may be recovered from the leachate solution by subjecting the leachate solution to conventional recovery techniques, such as electrowinning, solvent extraction, gas-reduction or adsorption, and in particular cementation.
