Geosynthetics use expands in mining and ore processing

August 1st, 2018

The estimated value of nonfuel mining of raw materials in the United States alone totaled $75.2 billion in 2017, according to an annual report by the U.S. Geological Survey (USGS). Everything from aluminum to zinc falls into this massive category, but that dollar figure is dwarfed by the USGS’s estimate in that same report of […]

Deploying a geosynthetic mattress ballast layer at an ore-processing site

August 1st, 2018

New applications of geosynthetics are being found that form from overlaps of existing functions, such as protection, separation, filtration and drainage. One new geosynthetic product, the geosynthetic mattress ballast layer (GBL), was first implemented for an ore-processing waste facility protection application in 2015. The GBL is a geotextile containment system that provides a tubular component […]

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 […]
