tested in the laboratory were coal waste tailings, gold tailings, oil sand composite consolidated tailings and copper tailings. Some of the basic properties and laboratory tests that can be conducted on mine tailings in order to better predict the behavior of the tailings are presented.
Tailings The gold content of the tails was completed on 62 samples. As one would expect, this showed less gold reporting to the tailings launder, but it was still on average about grams/tonne. The variance was also less, and this would be expected since the tailings would be less likely to receive any pieces of coarse gold moving along the riffles in the shaker table.
