The results showed that materials are so heterogeneous and highly supporting segregation and natural gravity sorting of waste rock materials from top to toe.
Average particle density (or specific gravity, Gs) of waste rock materials are 2.5 with standard deviation of 0.2 which is demonstrating the possible presence of coarser materials (light materials) in waste rock samples.
Conclusion The soil physical study of waste rock pile showed that materials are so heterogeneous and have soil-like behavior.
