An investigation into bioleaching of uranium and rare earth elements from quartz-pebble conglomerate ores from Elliot Lake, Ontario
… may be suitable for development of a sustainable heap-leach method for the extraction of U and REEs from the low-grade host mineralization, this thesis is focused on the geochemical and biological process simulation monitoring of the biogeochemical release of elements to the leaching solutions. …

Physical Performance of Geomembranes Used in Heap Leach Pad Applications
… are normally used as part of the liner system in heap leach pads. There is a need to quantify tensile strains in the geomembrane that could affect short-term puncture and long-term performance of the GMB. In this thesis, short-term tensile strains arising from indentations caused from the material …

Long-Term Performance of HDPE Geomembranes as Landfill Liners
… as municipal solid waste (MSW) landfills and heap leach pads. Field conditions, which include physical stresses on the geomembrane, elevated operating temperatures, and contact with leachate constituents, have the potential to affect the service life of the HDPE geomembranes. This thesis …

The Chemical Durability of Elastomeric Bituminous Geomembranes (BGMS) in Different Geoenvironmental Applications at Elevated Temperatures
… in synthetic municipal solid waste (MSW) leachate. It is shown that the 4.1 mm has slightly faster degradation in its chemical, mechanical, and rheological properties than the 4.8 mm BGM. Relative to the mining solutions, the degradation in the bitumen coat was slower in the MSW leachate, …
