  • Publication number: 20200318013
    Abstract: The present invention relates to a method for transporting, flocculating, and dewatering an aqueous tailings stream. Said method comprises adding a flocculant composition comprising a poly(ethylene oxide) (co)polymer with the aqueous tailings stream wherein the aqueous tailings stream has 15 wt % or less solids. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.

  • Patent number: 10794796
    Abstract: A novel, advanced polymeric swab is disclosed herein. The swabs have a surface texture that allows for independent motion between microscale regions, are reusable with no loss of accuracy or efficiency, and are fabricated from optoelectronically-active elements to minimize static charging during repeated use.

  • Publication number: 20190276345
    Abstract: The present invention relates to a process for flocculating and dewatering an aqueous mineral suspension. Said process comprises mixing a powdered poly(ethylene oxide) (co)polymer with the aqueous mineral suspension. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.
