• Description:
  "The U.S. Bureau of Mines Reno Research Center operated a batch pilot plant to demonstrate high-temperature cyanide leaching or recovering platinum group metals (PGM) from automobile catalysts. Approximately 1,600 kg of used pellet, monolith, and metal support catalyst containing 1,700 g (54 tr oz) of PGM were processed. Average extractions from the used pellet catalyst were 96 pct Pt, 95 pct Pd, and 73 pct Rh. Heating destroyed cyanide to less than 0.2 mg/L free and total cyanide. Both the pellet and monolith residues were evaluated for disposal using the EPA Toxicity Characteristic Leaching Procedure (TCLP)." - NIOSHTIC-2
