Abstract:

A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and after deposition and post-deposition (reclamation) behavior. This paper describes three case histories where finite strain consolidation theory was used for the engineering design and environmental planning of impoundments. Four materials are considered: sulfide tailings remaining from copper and zinc extraction, and gold tailings from three different ore bodies.
