Certified Reference Material: Iron Ore

Printable version of the certificate (PDF, 577.17 kb)

Reference ore MW-1 was donated to CCRMP in 1980 by the Quebec Cartier Mining Company. It is a concentrate of iron ore typical of Mount Wright, Quebec, and is essentially specular hematite containing minor and trace quartz, iron silicates, and ilmenite.

Fifteen laboratories provided analytical results for one or more of the 12 selected elements in MW-1. However, only 8 were ultimately certified.
