Over 20 years experience in mineral processing of precious and base metals including operations, troubleshooting and auditing. Extensive familiarity with analytical and metallurgical laboratory methodologies.
Prior to joining Chevron Energy & Technology Company, I worked at several gold mines, was employed ten years with Newmont International Services and Newmont Mining Corporation and was a consulting engineer for Behre Dolbear.
My specific project experience includes the following:
* Researched, developed, patented & engineered base metals catalyst (Mo, Ni, V) reclamation plants that are synergistic to vacuum residuum hydroprocessing and coal liquefaction units (Chevron);
* Process valuation of multiple marble and kaolin operations in Georgia, Alabama and Brasil (Imerys),
* Scoping study and process technology development for a Cu-Au deposit in Kyrgyzstan (Eurasian Minerals),
* Assay data reconciliation, using statistical techniques, from bench scale and pilot plant flotation tests for a feasibility stage base metal/PGM project in Finland (Gold Fields),
* Metallurgical valuation and pre-feasibility engineering update of a precious/base metals polymetallic deposit in Greece (European Goldfields),
* Owners Representative for project management and engineering oversight of a gold plant expansion in Venezuela (Hecla Mining),
* Valuation and process optimization audits on flotation plants, smelter and base metal refinery for a platinum group metals producer in Montana (Stillwater Mining),
* Decreased operating costs at several Nevada mineral processing precious metal plants by over $100,000/year (Goldfields Operating Co, Santa Fe Pacific Gold, Apollo Gold),
* Developed mine pit water treatment for soluble arsenic and antimony species to ground water discharge Federal environmental standards (Newmont),
* Developed process to eliminate mercury vapor from milling and refinery circuits, to MSHA standards, improving on personnel health and safety issues (Newmont),
* Researched and developed process to extract precious metals from refractory ore using pressure oxidation in ammoniacal thiosulfate medium (U of Nevada-Reno).
