MEND REPORT 4.3.1
April 1990

EXECUTIVE SUMMARY

RTS-1 and RTS-3 respectively are samples of highly oxidized and partially oxidized pyritic tailings from the Waite-Amulet tailings, Noranda, Quebec. RTS-4 and RTS-2 are respectively a pyrrhotite mineral concentrate and highly oxidized pyrrhotitic material from Ni/Cu/Co mining operations in Sudbury, Ontario. Under the Mine Environment Neutral Drainage Program (MEND) and CANMET, these samples were prepared as compositional reference materials for analytical method development and quality assurance applications for sulphide ore tailings studies.

Recommended concentration values for thirteen constituents of these materials were established from results obtained in an interlaboratory measurement program. Twenty-five values meet criteria for certification applied by the Canadian Certified Reference Materials Project. Informational values for twenty-two additional constituents were established from measurements by two to seven laboratories in each case.

This report describes the materials preparation, measurements and assessments applied in establishing the reference values. Samples of RTS-1 to RTS-4 will be made available through the Canadian Certified Reference Materials Project (CCRMP) of CANMET.
