Source
RTS-3a is a sulphide ore mill tailings obtained from an unoxidized zone of the Waite Amulet tailings, north of Noranda, QC, Canada.The raw material was donated by Xstrata Copper. The raw material for RTS-3a was obtained from the same source as its predecessor, RTS-3.
Description
The mineral species include: quartz (18.0%), pyrrhotite (16.6%),amphibole (15.1%), clinochlore (9.3%), K-feldspar (6.1%), vermiculite (6.0%), albite (5.8%), magnetite (5.7%), pyrite (5.0%), pyroxene (4.7%), cummingtonite (3.8%), muscovite (1.4%), gypsum (0.7%), ilmenite (0.5%), chalcopyrite and titanite (both at 0.3%), sphalerite and talc (both at 0.2%); and cassiterite, jarosite and tetrahedrite – tennantite (all three at 0.1%).
Intended use
RTS-3a is suitable for the analysis of various elements at major, minor and trace levels in tailings. Examples of intended use include quality control and method development.
