Definitions
- Oil sands which are also known as tar sands, are mixtures of clay, sand, water, and heavy hydrocarbons, such as bitumen. They provide a potential source of hydrocarbons for petrochemical industry.
- the conventional bitumen extraction methods use hot water and caustic soda to separate bitumen from sand and clay in a froth-flotation process.
- Tailings from the flotation process comprise water, particulate solids, such as clay, residual bitumen and natural surfactants.
- the invention is defined in the characterising parts of the enclosed independent claims. Some preferable embodiments of the invention are defined in the dependent claims. All described features apply both for the use as well as the method and composition of the invention, whenever applicable, even if it not necessarily stated so.
- the method comprises
- the flocculating agent comprises a cationic polyacrylamide.
- Cationic polyacrylamide is a copolymer of (meth)acrylamide and at least one cationic monomer, preferably a copolymer of acrylamide and at least one cationic monomer.
- Ch-lso was added at dosages of 0 g/t, 1000 g/t, 2000 g/t and 3000 g/t, while the flocculant polymer 1 dosage was between 80 and 190 g/t.
- the results the supernatant solids are shown in Figure 2A and results for settling rates are shown in Figure 2B at different Ch-lso dosages.

Abstract
L'invention concerne un procédé et une composition de traitement des résidus d'un processus de séparation, le bitume étant séparé des solides minéraux. Les résidus comprennent une phase aqueuse avec un matériau particulaire solide en suspension et du bitume résiduel et ont une teneur en solides secs < à 25 % en poids. Le procédé comprend l'ajout d'un agent floculant comprenant du polyacrylamide aux résidus, ainsi que l'ajout d'un agent auxiliaire comprenant un liquide ionique aux résidus conjointement à l'agent floculant. Des flocons, qui comprennent un matériau particulaire solide, sont formés et les flocons formés sont séparés de la phase aqueuse. La composition comprend un copolymère de (méth)acrylamide et un agent auxiliaire comprenant un liquide ionique.
