The role of ultrafine particles in oil sands fine tailings

The final volume of fine tailings depends on the ultrafine content in the oil sand ore, and not on the type and concentration of the electrolyte in th process water. Although modified extraction processes resulted in faster settling, the modification produced "dirtier" (containing more clay) secondary froths, thus bringing about other process problems.
