What is contained in a tailings storage facility?

Tailings, ground up rock (uneconomical ore after processing) plus water, are contained in the TSF. The composition of the tailings will vary depending on the composition of the rock in the surrounding environment and the process of mineral extraction used at each mine.

What is the water quality in a tailings management facility?

Water to be discharged from the TSF is regulated by the provincial Environmental Management Act and federal Fisheries Act.[1] [2]
