A Study for Leaching Synthetic Scheelite in H2SO4 And H2O2 Solution: An Investigation and Optimization
DownloadFall 2023
Canada's 2021 Critical Minerals Strategy underscores the prominence of tungsten as a rare and critical element. Today, tungsten production relies on scheelite, categorized as a secondary resource due to its complex ore composition and lower-grade nature. This phenomenon stems from the depletion...

Fundamental Study of Flotation Behaviors and Oxidation Mechanisms of Polymorphic Pyrrhotite and Pentlandite
DownloadFall 2021
This thesis is mainly concerned with understanding the flotation behaviors of the polymorphic pyrrhotite (Fe1-xS, 0 < x ≤ 0.125) and pentlandite ((Ni,Fe)9S8) to find better measures for their flotation separation. The flotation separation of pentlandite from pyrrhotite is a complicated issue due...

Fall 2018
As a spectroscopic matrix, helium nanodroplets exhibit many advantages over frozen rare gas matrices or other seeded clusters. Helium nanodroplets are superfluid, and interact only very weakly with embedded dopants, meaning high-resolution spectra are possible. Further, dopants are rapidly cooled...
