Transitioning the mining industry to sustainability with geosynthetics
December 31st, 2021
By Michael Dickey, P.E., Director, Presto Geosystems Geocells at a mining site. Photograph courtesy of Presto Geosystems Mined materials are essential to our everyday lives. We use these valuable minerals in nearly every sector of the economy—they are necessary to construct roads and buildings, manufacture vehicles, build computers and generate electricity. Additionally, the mining industry […]
Mining tailings management with geosynthetics
June 30th, 2021
Tailings are by-products, the materials that remain after the process of separating the target mineral from the uneconomic fraction of an ore. They are different from the waste rock or other material that overlies an ore or mineral body, which are displaced during mining without being processed. Tailings can be liquid, solid or a slurry […]
Multilinear drainage geocomposites to filter oil sands tailing slurries
October 1st, 2018
Mining and some energy operations generate large quantities of water-containing tailings. These tailings are made of crushed-rock particles that are deposited in a slurry form. This is the case for coal, tar sand, lead, zinc, gold, silver, copper, molybdenum, nickel, taconite (iron), phosphate, bauxite (aluminum oxide), uranium, trona (soda ash) and potash, for example. There […]
