Waste slurry from the process plant of this underground mining operation is deposited into tailings dams which was nearing maximum capacity. With strict environmental and water management regulations, a suite of solutions were implemented. 1) dewatering and cleaning the downstream polishing ponds 2) utilizing TenCate Geotube® units to capture fine contaminants in water pumped up from underground workings and 3) sediments in higher flows of water was recycled back to the old TSF from the new TSF.

The project has provided a wealth of knowledge in how to successfully install and operate large tubes over extremely soft substrates, and function as a high-volume water management tool, collecting and containing sediments within the confines of the TSF.
