Publication number: 20220055083Abstract: A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).Type: ApplicationFiled: September 7, 2021Publication date: February 24, 2022Inventors: Oladipo OMOTOSO, Adrian REVINGTON, Marc GORANSON, Patrick Sean WELLS, Macoura KONE, Daryl HOCKLEY, Baha Elsayed ABULNAGA, John DIEP, Benito MOYLS, Alan MELANSON, Rodney GUEST, Naveen PRATHAP, Babak DERAKHSHANDEH

Patent number: 9068776Abstract: Methods for drying oil sand fine tailings treated to comprise flocculated fine tailings, by deposition and farming techniques, are provided. A deposition cell is provided with a sloped bottom surface and the flocculated fine tailings are deposited to undergo channelless advancement in the cell while allowing drainage of release water. When the deposit is uneven, the deposit may be plowed while wet for spreading and ensuring water release conditioning is imparted thereto, while avoiding over-shearing, and maintaining sufficient shear strength to allow standing. Once a dried upper crust forms, the deposit may be harrowed to break up the crust, expose wet regions there-beneath and create furrows in the standing deposit. The methods improve the dewatering and drying of mature fine tailings in oil sands.Type: GrantFiled: October 30, 2009Date of Patent: June 30, 2015Assignee: SUNCOR ENERGY INC.Inventors: Trevor Bugg, Jamie Eastwood, Adrian Peter Revington, Marvin Harvey Weiss, Patrick Sean Wells, Thomas Charles Hann, Stephen Joseph Young, Hugues Robert O'Neill
