List of Tailings, Dams, Water supply dams Projects in WA


RAVENSTHORPE NICKEL PROJECT - TAILINGS STORAGE FACILITY
50 km north of, Hopetoun, WA 6348 Has Ravensthorpe Nickel Project - Tailings Storage Facility currently at Construction stage. Development will comprise a Tailings Storage Facility (TSF) to store a maximum of 87.81 Mt over a 25 year life. It is proposed that 3.51 Mtpa will be stored in the TSF. The TSF will comprise 3 cells of 180-190 Hectares each. The TSF will be using thickened tailings. This will reduce seepage induced groundwater impacts. This will be achieved by limiting the formation of a water pond on the tailings surface by thickening the tailings slurry prior to discharge, maximising evaporation from TSF and maximising transfer of liquid from the TSF to the evaporation pond. The evaporation ponds will be a maximum height of 2.9 metres and store annually 1.58 Mtpa. A permanent spillway will also be constructed. Click for more details...
