Carbofol174; high density polyethylene (HDPE) geomembranes feature exceptional chemical, stress crack, and UV resistance. Their durability and chemical compatibility is well supported by data and project records in tailings management.
The most extensive use of the geomembrane liners has been, and remains, in the construction of evaporation ponds and heap leach pads starting in the 1970s. Tailings impoundments have historically been mostly soil lined, but increasing in their use of geomembrane liners in recent times. This paper will present an overview of the geomembrane

The Nye Tailings Impoundment continues to provide secure storage of fine grained tailings Placement of the Closure Cap will consolidate and densify the saturated fine grained tailings. Increasing the Closure Cap thickness will enhance the stability of tailings impoundment and allow for additional waste rock to be integrated into the post
This paper presents an innovative approach to lining steep to vertical rock faces with a geosynthetic system consisting of slope reinforcement, liner cushioning, and geomembrane, for an expansion of an existing tailings storage facility.
Geomembrane made from hdpe, ldpe, lldpe, pvc, eva are the preferred products for lining projects requiring low permeability , corrosion protection , exceptional chemical and ultraviolet resistance properties , which makes them extremely cost effective for many applications such as waste landfill , storage reservoirs , canals , gas and oil plants in energy , underground water detect, vapor barriers ,
Reinforced Polyethylene (RPE) has been used as a geomembrane material for over 20 years. Common uses of RPE's are canal liners, drilling sump liners, soil remediation liners, tailings dam liners, and interim landfill caps.
HDPE Geomembrane made from high density polyethylene resin by blow film process. Complete line of smooth and textured HDPE geomembranes combines long term durability with strength, flexibility, and ultraviolet and chemical resistance to provide an impermeable barrier for a wide variety of applications.
GSE uses the highest quality resins to manufacture the widest selection of high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) geomembrane products available in either a black, green or white upper surface, and in either a smooth or textured single or double sided surface.
Landfills, tailings impoundments, and heap leach pads are the largest and highest geomembrane lined fill structures in the world. These lined structures require large areas for storage and containment of solid wastes, precious or base metal mill waste tailings, and ore heap fill materials.
For the past few years, KCB has collaborated on several geomembrane research projects with Prof. R. Kerry Rowe and his team at the Geo Engineering Centre at Queens University in Kingston, Ontario. The research is assessing the effectiveness of geomembrane liners in tailings storage facilities (TSFs).
Geomembrane installations can be a single layer of geomembrane on prepared subgrade, two layers of geomembrane for addition protection, reduced head on the secondary liner and the added benefit of leak detection capabilities, or it can be a geomembrane over a low per meability soil layer, referred to as a composite lining system.

Research Update on Geomembranes at Tailings Storage Facilities Posted on August 8, 2017 Professor Kerry Rowe and Klohn Crippen Berger (KCB) alumnus Alan Chou of the GeoEngineering Centre at Queens University recently presented an update to KCB staff on the use of geomembranes at tailings storage facilities (TSFs).
An important function of these tailings facilities is to prevent the uncontrolled release of material into the environment during operation and closure. These facilities are often set up as settling ponds and dams lined and later capped with a geomembrane or textile.
Professor Kerry Rowe and Klohn Crippen Berger (KCB) alumnus Alan Chou of the GeoEngineering Centre at Queens University recently presented an update to KCB staff on the use of geomembranes at tailings storage facilities (TSFs). This update is a result of a multi year research program, partly funded by KCB, involving fellow researcher Professor Richard Brachman, and KCBs Dr. Prabeen Joshi and Harvey
ticularly tailings storage facilities (TSFs), presents unique challenges including fixed facility lo cations, sequential construction schedules, construction season and weather related constraints, and difficulties in sourcing specialized materials and contractors.
At tailings storage facilities, a geomembrane may be used to contain tailings from relatively more permeable foundation or embankment materials.
Textured geomembrane is also utilized beneath earthworks structures that sit above the liner, such as the main drains, decant towers, and access causeway, to ensure stability prior to tailings deposition.
The half life of HDPE geomembranes has been estimated through laboratory testing of samples and monitoring of existing lined impoundments (Tarnowski and Baldauf, 2006). Laboratory testing involves incubating samples of HDPE geomembrane at high temperatures
