Spring 2014
Several series of quaternary chalcogenides were synthesized by high temperature reactions and their crystal structures were determined by X-ray diffraction methods. Differences in electronic structure were examined by X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge...

Surface Oxidation of Millerite and its Galvanic Interaction with Chalcopyrite in Collectorless Flotation
DownloadFall 2021
Surface analysis of millerite and chalcopyrite were performed to enhance the understanding of fundamental millerite flotation behaviour in single mineral and mixed mineral conditions. By studying the mineral surfaces without collector addition, the ambiguity about the origin of the formed...
