Source
CZN-4 is a zinc sulphide flotation concentrate donated by Xstrata Copper Canada Division, Kidd Metallurgical Site, Timmins, Ontario, Canada. The raw material was obtained from the same source as its predecessor, CZN-3.
Description
The mineral species include: sphalerite (90.6%), pyrite (4.1%), pyrrhotite (3.3%), iron oxides (0.5%), quartz (0.5%), chalcopyrite (0.3%), various other silicates (0.2%), ankerite (0.1%), arsenopyrite, cassiterite, chlorite and galena (all at 0.1%).
Intended use
CZN-4 is suitable for the analysis of zinc and various other elements at major, minor and trace levels in zinc concentrates. Examples of intended use include quality control and method development.
Instructions for use
CZN-4 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.
