Molybdenum ore, PR-1 : its characterization and preparation for use as a standard reference material / the staff of the Mineral Sciences Division. : M34-20/139E-PDF
“To fulfil a need of Canadian industrial and commercial laboratories, the Mines Branch of the Department of Energy, Mines and Resources has undertaken a program to produce a number of standard reference ores of metallic minerals. This report describes the characterization of molybdenum ore, PR-1, and its preparation for use as a standard reference material. The mineralogical, geological and chemical characteristics of PR-1 are given as well as the details of the methods used for its comminution and blending and for assessing its homogeneity. Nineteen laboratories participated in the program by providing analytical results for molybdenum, bismuth, iron and sulphur. All these results and the evaluation of their statistical parameters are reported for each of the four elements. Recommended values of the means and their confidence limits are given"--Synopsis, p. i.
