Abstract
The invention relates to a use of a reversible molten salt for separating hydrocarbons, such as crude bitumen and/or heavy crude oil, from material comprising mineral solids. The invention relates also to a method comprising at least the steps of: (a) bringing a liquid phase comprising a reversible molten salt, preferably a reversible ionic liquid, in a contact with mineral solids comprising hydrocarbons and extracting hydrocarbons to the liquid phase from the mineral solids; (b) separating the mineral solids phase from the liquid phase, which comprises molten salt and hydrocarbons; (c) separating hydrocarbons from the liquid phase comprising molten salt; and (d) recycling the liquid phase comprising molten salt to step (a).
