MP-2a is suitable for the analysis of tungsten, molybdenum, bismuth, the rare earth elements and various other elements in ores in concentrations ranging from major, minor to trace levels. Examples of intended use include quality control and method development.
MP-2a is a tungsten-molydenum ore obtained from the Mount Pleasant property in New Brunswick, Canada. The raw material for MP-2a was donated by Adex Minerals Corp and was obtained from the same source as its predecessor, MP-2.
The mineral species include: quartz (64.9%), topaz (6.3%), clinochlore (5.1%), fluorite (5.1%), muscovite (5.1%), almandine (3.3%), orthoclase (3.0%), plagioclase (1.9%), sphalerite (0.8%), wolframite (0.8%), arsenopyrite (0.7%), other (0.6%), epidote (0.5%), Fe-alloy (0.3%), pyrite (0.3%), galena (0.3%), calcite (0.2%), loellingite (0.2%), magnetite (0.2%), molybdenite (0.2%), monazite (0.1%), bismuth (0.07%), cassiterite (0.05%), chalcopyrite (0.04%), euxenite (0.04%), rutile (0.03%), zircon (0.03%) and keiviite (0.02%).
