Mineralogical characterization and paragenesis of the Cripple Creek deposit, Colorado
… and developing a new model that describes the mineralogical evolution of the deposit. In addition, this thesis explores the nature of gold-bearing As-rich pyrite as sampled from different regions within the deposit. This thesis presents information derived from detailed mineralogical …

Mineralogical Characterization of Uranium Ores, Blends and Resulting Leach Residues from Key Lake Pilot Plant, Saskatchewan, Canada
The production and storage of uranium mine mill tailings have the potential to contaminate local groundwater and surface waters with metals and metalloids. As such, an understanding of the solids reservoirs for potential contaminants in uranium ore blends and leach residues (solid wastes generated …

Mineralogical characterization of South African mine tailings with aim of evaluating their potential for the purposes of mineral carbonation
… annual CO₂ produced at Secunda, South Africa. A mineralogical investigation into the mineral carbonation potential of mine tailings was conducted using samples from seven mining companies. Four of the mining operations considered (Impala, Rustenburg, Amandelbult and Mogalakwena) are PGM …

Geochemical, Isotopic, and Mineralogical Characterization of the Frobisher Suite Mafic-Ultramafic Sills, Southern Baffin Island, Nunavut, with Implications for Metallogenic Potential
The Frobisher Suite is a newly recognized magmatic province comprised of mafic-ultramafic sills in southern Baffin Island, Nunavut. The sills are emplaced into the metasedimentary strata of the middle Paleoproterozoic Lake Harbour Group, and vary in thickness from several meters to hundreds of …

Sulfate Dynamics and Base Cation Release in a High Elevation Appalachian Forest Soil
… inputs. After initial physical, chemical, and mineralogical characterization, the soils were analyzed for their ability to adsorb and retain sulfate (SO₄²⁻) through a series of batch adsorption and desorption experiments. Reconstructed soil profiles were then subjected to water leaching as the …

Structure-property relationships of earth and engineered materials
… and tuning profitable materials. A comprehensive characterization of the structure of minerals and materials (from their atomic- to microstructure) is necessary for their full and informed implementation. This dissertation considers three overarching areas of research in which mineral and material …

A Process Mineralogical Study on the effect of Alteration on the Flotation of Great Dyke Platinum Group Element (PGE) Ores
… This study focusses on identifying the key mineralogical differences between three Great Dyke platinum group element (PGE) ores in Zimbabwe. These ores are known to be characterized by extensive oxidation and alteration resulting in numerous metallurgical challenges in recovering the PGE. …
