Cellular automata consistently grow in relevance to engineering and science as computation becomes more important for design and theoretical analysis. Although cellular automata have been used for a variety of tasks a means of representing objects has not yet been devised. This is a severe...
An Investigation of Millerite (beta-NiS) Flotation Behaviour in Alkaline Solutions in Cu-Ni Sulphide Mineral Flotation SeparationDownload
In the Sudbury Basin nickel deposit, the presence of a less common nickel sulphide mineral – millerite (beta-NiS) has a substantial impact on the Cu/Ni flotation separation efficiency. In this study, the flotation chemistry of millerite in alkaline solutions was investigated with pure minerals...
CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands ExtractionDownload
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...
Selenium is an essential trace element nutrient for human life, but it can be extremely toxic if taken excess. Various adsorbents have been applied for the removal of selenium from water but performed poorly in the removal of Se (VI), which is more bioavailable and more difficult to remove....
Design, Synthesis, Characterization of a new pH-Responsive Copolymer and its Application in Oil Sands Tailings TreatmentDownload
This research aims at treating mature fine tailings (MFT) with a novel pH-responsive copolymer poly (N,N-dimethylaminoethyl methacrylate-co-acrylamide-co-acrylic acid) p(DMAEMA-co-AM-co-AA). Compared with conventional polyacrylamide (PAM), the conformation and property of this novel copolymer can...
Hot water extraction technique has been applied to extract bitumen from oil sands for decades. With the challenge of low oil prices, achieving higher recovery and efficient production becomes more urgent. In recent years, the overall recovery and froth quality have been improved significantly...
Among all the competing methods to enhance the phase separation of water-in-oil emulsions in chemical industries, electric field is considered as one of the best treatment options. To better understand the mechanism by which electric field assists water droplets coalescence and the corresponding...
Albertan oil sands ores are becoming more difficult to process efficiently as the clay content of the ore increases and the grade of the ore worsens. A key to improving the extraction of bitumen from low-grade oil sands, thereby increasing the longevity of this critical resource, is reducing the...
Rapid, efficient and economical water removal from fluid fine tailings represents a major challenge to many industries, including mineral processing, food processing, waste water treatment and oil sands extraction. In the absence of large-scale fine tailings processing facilities, there will be...
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...
