latter method resulted in lower cyanide consumption and increased PGM recovery. Pre-roasting of UG-2 in air (at temperatures greater than 800°C) converted PGM sulphides to oxide phases and native metals and alloys2. HCl/chlorine leaching gave much improved recoveries of platinum (Pt), palladium (Pd), and
