Geosystems for Mining and Minerals Technology

One Total Solution For Mining And Mineral Processing
TenCate Geotube® dewatering technology provides a simple and cost effective way of dewatering large and small volumes of Mining and Mineral wastes. This proven technology can accommodate dewatering and containment in one, cost-effective operation. Utilizing TenCate Geotube® containers is an effective alternative to mechanical processing that enables the capture of precious metals and the efficient management of mine tailings, coal sludge, and other mine waste streams. With volume reduction as high as 90%, high solids levels make removal and disposal easy.

TenCate Geotube® containers can be custom-sized to fit available space and be easily removed when dewatering is complete. Dewatered solids can be safely stored on site, re- utilized to build dykes and berms, or disposed of in a landfill without expensive dredging or transportation.

Pond & Lagoon Maintenance
Maintaining key water quality discharge parameters and sufficient free board for continuous operation is of the highest priority at all mining operations. The major environmental concern with wastewater lagoons is the potential leakage to groundwater. Wastewater can contain a range of pollutants (e.g. organics, nutrients, salts, metals) either acidic, or alkaline. Often hazardous substances require the highest level of care. Overtopping of a full lagoon or compromised pond liners can lead to leakage and environmental concerns.

Through continuous or event driven pond maintenance dewatering programs to insure sufficient capacity, TenCate Geotube® dewatering and containment technology provides a simple, low cost solution. easy to set up, even in remote locations, TenCate Geotube® dewatering technology can quickly be deployed to reduce lagoon levels or be used to contain the full volume of dewatered waste material for a complete cleanout.

Tailings Management
“Tailings” refer to the end of the mining process, constituting what is left over after the substances of economic value have been removed. They generally consist of ground rock and process effluents that are generated in a mine processing plant. Tailings are commonly storedin an impoundment – an engineered structure – used as a settling basin/storage container. Management of these storage basins is critical to a mining operation to insure there is sufficient capacity to keep the mine running.

Adding additional capacity is often done by raising the perimeter of the basins, or removing and dewatering the built up sediments in the storage ponds. TenCate Geotube® dewatering technology delivers a high volume, low cost solution reducing disposal costs by consolidating higher solids with very little maintenance. Dewatered solids can be safely stored on site, within the container, eliminating the spread of airborne particles or mechanically removed and transported to an approved location. In many cases, dewatered tailings contained inside the Geotube® units canbe used as a structure within the pond or placed on top of the perimeter of the berm to provide additional capacity.
