Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...
Efforts related to the safety and performance of oil sands tailings storage and transportation facilities have traditionally focused on preventing catastrophic failures. However, a recent death related to ground hazards near oil sands tailings facilities, dykes, and transport systems illustrates...
The study investigated the feasibility of using the soil freezing characteristic curve (SFCC) to estimate the soil water characteristic curve (SWCC) in mine waste tailings as an alternative to traditional SWCC testing. Traditional SWCC tests are challenging and time-consuming to conduct, taking...
The production of a tailings waste stream is ubiquitous to mining and mineral processing operations, especially in Alberta’s oil sands industry. Due to the presence of colloidal clays such as kaolinite, which do not naturally sediment in suspension, water recycling and land reclamation remain...
The focus of the research presented here was to directly measure actual evaporation rates from a tailings surface using a micrometeorological technique known as the eddy covariance method. Depending on the results, it would be determined whether current drying models need to be calibrated with...
Oilsands tailings are a waste product comprising primarily a stable alkaline suspension of clay in water. This waste product of oilsands mining is environmentally hazardous to store and expensive to safely dispose of. This work presents two novel ideas for dealing with the waste. The first is...
Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....
Effects of Surface Contamination and Water Chemistry on the Behaviors of Illite, Kaolinite and Montmorillonite in Organic and Aqueous MediaDownload
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...
Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands TailingsDownload
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...
A multi-purpose settling column was designed to determine settling rate and sediment height allowing the in-situ measurement of yield stress and drainage without disturbing the sediment particle network. The settling column was applied to studying flocculation/densification of model oil sands...
