Technical Report Design And Evaluation Of Tailings Dams
Slimes are often used to line the upstream face of tailings dams (or lifts). Although slimes may offer a lowcost alternative to other materials, they have several disadvantages that are discussed in Vick (1990) and Ritcey (1989). In addition, it is difficult to determine longterm permeabilities of the slimes.
