Abstract
The mining of oil sands ore and extraction of bitumen produces aqueous slurries containing bitumen, coarse sand and fine clays. The performance of key process units is highly dependent on the rheology of “carrier fluid”, which is comprised of the fine solids and water. Although viscosity is important in process design and monitoring, it is rarely measured and instead determined using correlations. Viscosity depends on numerous factors including fines concentration, solids mineralogy and water chemistry - properties reflected in the size of aggregates formed by agglomerating solid species. More accurate correlations could be obtained by using additional correlating parameters. In this project rheology measurements were obtained using a concentric cylinder rheometer and compared with fines and aggregate volume fractions determined from particle image analysis. Multiple linear regression of key variables provided an equation to predict viscosity using fines content and calcium ion concentration as correlating parameters.
