Abstract The U.S. Bureau of Mines operated a 2,000-g (4.4-lb) batch process development unit for recovering platinum group metals (PGM) from automobile catalysts. Virgin monolith, used pellet and used monolith catalyst samples were tested. Leaching twice with 1-pct sodium cyanide (NaCN) solution at 160 deg C for 1 h dissolved over 95-pct of the PGM from virgin catalysts and over 90-pct from used pellet catalysts. The used leach residues passed the EP Tox Test for all elements but failed the WET and TCLP for Pb.
