Abstract
A method for separating hydrocarbons from an initial mixture comprising agglomerates (200) of hydrocarbons and solid inorganic material (212) is disclosed. The method comprises the steps of grinding the agglomerates by exposing the initial mixture to a liquid dissolving agent and a medium (123, 123′) having kinetic energy, removing a film of hydrocarbons (211′) from the inorganic material (212) using cavitation and/or ultrasound, and separating liquid from the solid inorganic material (212). Compared to prior art, the method provides better separation and low consumption of heat, organic solvent and water. An apparatus and a system are also disclosed.
