Dewatering options for management of fine gold tailings in

Typical tailings disposal systems in the Western Australian Goldfields consist of tailings paddock facilities, where tailings are discharged either from a single outlet or from spigots around a ring dyke. Upstream raising and central decanting of supernatant water is common practice. Potential evaporation in this region is high, at around 2 m per year, with summer months accounting for more
