    On sub-aerial deposition, the tailings undergo hydraulic sorting down a delta that forms at a slope of between 1 in 50 and 1 in 150 (averaging about 1 in 100), settling and sedimentation, and self-weight consolidation. Hydraulic sorting of the tailings takes place due to particle size and Gs differences.
