Title: Leaching of petroleum catalysts with cyanide for palladium recovery. Report of investigations/1995

Abstract

The U.S. Bureau of Mines has tested cyanide leaching for recovery of Palladium (Pd) from spent petroleum processing catalysts. Three different catalyst samples were supplied by Gemini Industries, a spent catalyst processor. These catalysts consisted of a zeolite base and contained 0.4 to 0.7 pct Pd. During alkaline cyanide leaching, the catalysts exhibited ion exchange properties due to their zeolite matrices. This could present a safety hazard due to the potential for release of toxic hydrogen cyanide gas. The catalyst leach residues passed the Federal Toxicity Characteristic Leaching Procedure and the California Waste Extraction Test, indicating that landfill disposal of the leach residues would be acceptable.
