A Geometallurgical Approach to Assessing Critical Metal Mobility and Recoverability from Ultramafic Mine Tailings
DownloadFall 2022
Critical metals (e.g., nickel and cobalt) are increasingly in demand for the production and storage of cleaner energy but their supplies are finite. Ultramafic mine tailings could be reprocessed as a source of critical metals. These waste materials host an array of critical transition metals and...

Empowering the Base Metals: Rational Design of Homogeneous Catalysts for Hydrotreatment, and Reduction of Organic Unsaturates
DownloadFall 2013
Hydrocarbon-soluble, low-coordinate, phosphoranimide-supported complexes of the base metals (iron, cobalt and nickel) were developed and evaluated for a range of stoichiometric and catalytic bond-forming and bond-breaking transformations. An unprecedented family of tetrametallic clusters of Co(I)...

Investigation of pathways of CO and CO2 in a Fischer-Tropsch system using tracer studies, development of reaction mechanism and kinetic expressions
DownloadFall 2015
The Fischer-Tropsch (FT) synthesis is an indirect feeds-to-liquids process to produce synthetic crude oil from any carbonaceous source such as coal, natural gas or biomass. The carbonaceous source is converted to synthesis gas by gasification or reforming, which then undergoes simultaneous...
