1 Introduction Sand dunes are an important part of the terrestrial landscape system on the Earth's surface (Thomas and Wiggs, 2008)They are widely distributed in arid and semiarid climate regions around the world, presenting a variety of aeolian landforms (Li, 1985, Wu et al, 2017)Modern dune deposits record the lithology of the parent rocks and a set of information Rare earth element mining projects are characterized by specific particularities as well as the potential presence of radiation Thus, there is a need for a set of REEspecific criteria and indicators to supplement Global Reporting Initiative–based indicators This chapter identifies existing indicator sets and lays out the importance of Rare Earth Element an overview ScienceDirect Topics The concentration of rare earth elements in a Canadian oil sand ore and six oil sand waste streams were examined using Inductively Coupled Plasma Mass Spectrometry (ICPMS) The results indicated that the rare earth elements (REEs) are largely concentrated in the TSRU tailings, similar to typical froth floatation tailings, with a total rare Rare Earth Elements in Alberta Oil Sand Process Streams
