Carbon Dioxide Amended Tailings

Canadian Natural Resources Ltd is adding C02 to its tailings lines to accelerate the pace at which tailings materials consolidate and reduce the size of tailings ponds. Read More

Tailings Reduction Technology

Accelerated Fines Drying and TROTM have the potential to reduce the time it takes to reclaim tailings ponds and eliminate the need for tailings ponds. Read More

Tailings Centrifuge

The environmental benefit of centrifugation is immediate as it speeds the release of water from Fluid Fine Tailings. Read More

Filter Press Project

The Filter Press is a technology that COSIA companies are assessing to speed water reclamation by mechanically pressing water out of Mature Fine Tailings. Read More

Cross Flow Filtration

Cross Flow Filtration is designed to remove greater volumes of water from the total tailings stream. It could also reduce the volume of Fluid Fine Tailings stored in existing tailings ponds. Read More

Accelerated Dewatering

Accelerated Dewatering provides a practical way of treating large volumes of Fluid Fine Tailings. Read More


COSIA’s Tailings Environmental Priority Area (EPA) is focused on improving the management of oil sands tailings. Tailings are the sand, silt, clay and water found naturally in oil sands that remain following the mining and bitumen extraction process.

Working with universities, government and research institutes, other companies and partners, the Tailings EPA is bringing together the shared experience, expertise and financial commitment of oil sands mining companies to find new technologies and solutions to tailings.

The Tailings EPA has identified key issues facing the industry and is working to address the following:

  • the accumulation of fluid fine tailings (FFT) within tailings ponds through the development of new and improved tailings management technologies;
  • treatment of process affected water, the water which remains once the FFT are removed; and
  • accelerating the reclamation of the resulting tailings deposits so that they can be incorporated into the final reclaimed landscape.

COSIA and Alberta Innovates – Energy and Environment Solutions (AI-EES) recently released a Tailings Technology Roadmap and Action Plan Project, a collaboration that also involved Alberta Energy, Natural Resources Canada, Alberta Environment & Sustainable Resource Development and the Alberta Energy Resources Conservation Board.  This plan provides a comprehensive review of technologies that will help industry identify a suite of actions that will accelerate the development of new and improved commercial tailings treatment technologies.

COSIA is the overarching collaborative hub within which companies set priorities, drive and share innovation and accelerate the pace of environmental performance improvements.

Examples of current projects include:
