Dr. Liuyin (Lucy) Xia

Surface Science Western

Career History

 Postdoctoral associate and research assistant in the UWO, Surface Science Western with the Dr. Hart group since 2012. Previously an assistant professor at CentralSouthUniversity, department of Chemistry and Chemical Engineering (2009-2011) working on nonferrous metal beneficiation and utilization. Also as a minerals engineer worked in Lab of Resources Chemistry of Nonferrous Metals of China studying chalcopyrite and bauxite floatation recovery.

 

Research interests

 Application of chemistry methods, such as scanning electron microscopy (SEM), time of flight secondary ion mass spectrometry (ToF-SIMS), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction, zeta potential, Atomic force microscopy (AFM), contact angle to understand the direct surface chemical characterisation of mineral grains from different streams and identify factors controlling process efficiency with an overall goal of improving metallurgical performance. In flotation separation, surface chemistry is the principle determinant for selective separation of the various minerals. For that reason, an enhanced understanding of factors operating on the surface of minerals will potentially provide opportunities for modifying the flotation scenarios, promoting improved selectivity and discrimination of the value and non-added value minerals to selective streams.
