Description
The source material for CH-4 was donated by Corporation Minière Inmet, Division Troilus, Chibougamau, Quebec in 2000. After crushing, milling, sieving and blending, the yield was 37%. The material is a fine powder with a mesh size of less than 45 μm (325 mesh) which comes in a glass bottle containing 200 g. This is the only size available. The host rock of the raw material is meta-anorthosite. The mineralogy includes pyrrhotite, pyrite and chalcopyrite, and small amounts of sphalerite, galena and molybdenite.
