  • What are oil sands tailings?
  • This extraction process generates fluid wastes called oil sands tailings . Although oil sands deposits are a great energy resource, tailings pose serious environmental concerns for Canada. Typically, mature fine tailings (MFT) contain fine negatively-charged clays (33 wt%), water (65 wt%), and fugitive bitumen (2–5 wt%) .
  • Can cationic polymers effectively flocculate oil sands tailings ponds?
  • This study demonstrates the potential of designing cationic polymers that effectively flocculate oil sands tailings ponds, and also further dewater the resulting solids through polymer degradation. The Supporting Information is available free of charge on the ACS Publications website at DOI: 10.1021/acsami.7b10302.
  • What technologies do oil sands companies use to treat MFT?
  • Over the last couple of decades, oil sands companies used technologies such as composite tailings, polymer-assisted flocculation, centrifugation, and freeze–thaw to address the issues associated with MFT treatment .
  • Is vbtmac a suitable flocculant for enhanced dewatering of oil sands?
  • This investigation introduced a new polymer flocculant for the enhanced dewatering of oil sands mature fine tailings. The monomer VBTMAC polymerizes rapidly in aqueous free radical polymerization to produce relatively high molecular weight poly (VBTMAC) that appears to be a good candidate for the flocculation of MFT.
