Rare Earth Elements in Alberta Oil Sand Process Streams

摘要: The concentrations of rare earth elements in Alberta, Canada oil sands and six sand waste streams were determined using inductively coupled plasma mass spectrometry (ICP–MS). results indicate that the (REEs) are largely concentrated tailings solvent recovery unit (TSRU) sample compared to itself. concentration lanthanide is ∼1100 mg/kg (1100 ppm or 0.11 wt %), which represents a >20× increase itself >7× North American Shale Composite (NASC). process water, used extract from sands, water fraction associated with different had very low REEs near below detection limits instrument, highest total being less than 10 μg/L (ppb). Size density separations completed, other potentially interesting valu...
