520 |a“Two reference materials containing platinum-group metals have been certified as standards. A concentrate from an alluvial material (containing platinum alloys) from the Tulameen River area of British Columbia has been analyzed for platinum; a nickel-copper matte from the Sudbury area of Ontario has been analyzed for platinum, palladium, rhodium, and gold. The sample preparation and characterization of the reference materials are described and a statistical evaluation of the "round-robin" analytical values has been performed. These reference standards are now available from the Mineral Sciences Division, Mines Branch, Department of Energy, Mines and Resources, Ottawa. A program for analyzing the nickel-copper matte for iridium, ruthenium, silver, and, possibly, osmium is to be undertaken. If sufficient satisfactory results are obtained, these constituents will also be certified for this material"--Synopsis, p. i.
