Abstract
A process is provided for capturing fines present in fluid fine tailings, in particular, in oil sands fluid fine tailings (FFT), present in a tailings containment structure by spreading coarse sand into the tailings containment structure below an interface that has formed between a water cap and the fluid fine tailings to form a uniform, non-segregating and homogenous fines-rich, a high total solids content mixture that will ultimately form a beach below FFT (BB-FFT) at the bottom of the tailings containment structure.
