Thickened Tailings Drying Project

Fort McMurray, AB, Canada

The Thickened Tailings (TT) project at Jackpine Mine is a commercial demonstration of technologies available to meet the Energy Resource Conservation Board (ERCB) directive 74 Tailings Performance Criteria and Requirements for Oil Sands Mining Schemes in Alberta, relating to fines capture and fines strength increase.

Different flocculent levels are added to the Mature Fines Tailing (MFT) stream, which originates from the External Tailings Facility (ETF), this mixture is then discharged into specially engineered drying cells that separate water and other fluids and leave behind a sludge material.  The hybrid material remaining in the cells is then allowed to dry naturally and over time becomes a substance that possesses engineering properties which comply with ERCB requirements.

Klohn Crippen Berger was Shell Canada Energy’s primary consultant for all engineering requirements for this project. Our remit was to provide the Client with a holistic engineering design for this distinctive and high-profile project.
