Source
SU-1b is a nickel-copper-cobalt ore from Copper Cliff, Ontario, Canada. The raw material was donated by Vale Inco Limited, and was obtained from the same mine as its predecessors, SU-1 and SU-1a, which are no longer available.
Description
The mineral species include: pyrrhotite (24.4 %); plagioclase (21.8 %); quartz (11.0 %); magnetite (7.3 %); ferrohornblende (6.7 %); pentlandite (5.4 %); clinochlore (5.2 %); K-feldspar (4.5 %); chalcopyrite (3.3 %);  pyrite (3.2 %); enstatite (1.5 %); epidote (1.3 %); augite (1.0 %); biotite (1.0 %); talc (0.6 %); various other minor silicates (0.5 %); actinolite (0.4 %); hypersthene, ilmenite and titanite, all at 0.2 %; and barite, berthierine, dolomite and  lizardite, all at 0.1 %.
Intended use
SU-1b is suitable for the analysis of nickel, copper, cobalt, platinum, palladium and various other elements at major, minor and trace levels in ores.  Examples of intended use include quality control and method development.
Instructions for use
SU-1b should be used “as is”, without drying. The contents of the bottle should be thoroughly mixed before taking samples.  The contents of the bottle should be exposed to air for the shortest time possible. Unused material should be stored under an inert gas in a desiccator, or in a new, heat-sealed laminated foil pouch.  The values herein pertain to the material when produced. CanmetMINING is not responsible for changes occurring after shipment.
Handling instructions
Normal safety precautions for handling fine particulate matter are suggested, such as the use of safety glasses, breathing protection, gloves and a laboratory coat.
Method of preparation
The raw material was crushed, ground and sieved to remove the plus 74 µm fraction.  The recovery was 82%.  The product was blended, and then bottled in 200-gram units.  Each bottle was purged with nitrogen and sealed in a laminated polyethylene - foil pouch.
