The technique of Inverse Gas Chromatography (IGC) was employed for the study of the interactions between various organic solvents with various types of the major inorganic materials (clay minerals and sand) found in Alberta’s oil sands. Heat of adsorption (-∆H) was measured for each solvent with...
In this work, the influence of solution salinity on settling performance of both commercial polymeric flocculant Magnafloc 1011(MF) and synthesized polymer flocculant Chitosan-graft-Polyacrylamide (chi-g-PAM) was systematically investigated. The effect of MgCl2 on the settling performance of MF...
Conaid is a liquid ionic soil stabilizers used as a compaction aid or a stabilizer for soil improvement. The material is a mixture of surfactant, stabilizer and high-charge ion sulfide compound. This product may have the potential benefits of removing absorbed water from soil particles with the...
Molecular Dynamics Study of the Interactions between Cations/Carbon Dioxide and Selected Mineral SurfacesDownload
Undoubtedly, we need to become increasingly aware of the changes and problems introduced to our environment. Oil sands industrial waste disposal and greenhouse gas emission are the two major by-products of the industrial processes that cause environmental concerns, such as huge tailing ponds and...
Dewatering of the oil sands mature fine tailings (MFT) is studied through pressure filtration following treatment by dual polymer flocculants. Polymer pairs consisting of anionic polyacrylamide (A3335) and cationic polyDADMAC (Alcomer 7115), and A3335 and non-ionic polyethylene oxide (PEO) are...
Kaolinite is one of the most commonly-used clay minerals in the production of paper, plastics, and ceramics, etc. However, kaolinite is also a hard-to-remove mineral in the processing of valuable minerals or energy resources, such as bauxite, metal sulphide ores, and oil sands. The main problem...
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...
Design and maintenance of coarse-particle Newtonian slurries pipeline requires the knowledge of carrier fluid viscosity. Since measurements of carrier fluid viscosity are difficult, numerous empirical correlations are typically used to predict this value. The main deficiency of available...
