| 520 | |a"A 228-kg sample of copper-silver-gold sulphide ore from Chibougamau, Quebec, has been prepared as a compositional reference material for gold. The material, encoded CH-1, was ground to minus 74 um and mixed in one lot; approximately 96 kg were bottled in 200-g units. The remaining 132 kg of CH-1 were blended with 17 kg of gold reference ore MA-1, screened to pass minus 46 um and bottled in 200-g units. The latter, encoded CH-2, was tested for homogeneity with respect to gold content by a fire assay-atomic absorption procedure"--Synopsis, p. i. |
