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 […]

Testing a new method for mining-waste storage using polymer-enhanced geosynthetic clay liners

July 31st, 2018

Geosynthetic clay liners (GCL) and polymer-modified geosynthetic clay liners (PMG) are gaining favor for use in industrial waste disposal and ore-processing applications (Athanassopoulos et al. 2015, Donovan et al. 2016a, Donovan et al. 2016b). The GCL or PMG can be a component of a composite liner system that will allow for increased performance (relative to […]
