Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 21). “A sulphide flotation concentrate from Sudbury, Ontario, has been prepared and characterized as a standard reference material for platinum, palladium, rhodium, gold, and silver. The recommended values for the contents of these elements in oz/ton are as follows: platinum 0.087, palladium 0.37, silver 0.17, rhodium 0.018, and gold 0.019. Several iridium, ruthenium, and osmium contents were reported by the laboratories that participated in the "round-robin" analytical program and these have been included in this report. The sample preparation and characterization of the reference material are described and a statistical evaluation of the analytical values has been performed"--Synopsis, p. i.
