Claim:
1. A method of handling a solvent-containing solids stream in a non-aqueous oil sand extraction process, the method comprising at least the steps of: (a) providing a solvent-containing solids stream at a first pressure; (b) depositing the solvent-containing solids stream provided in step (a) as a bed in a vessel; (c) discharging the solvent-containing solids stream from the vessel at a second pressure via an outlet comprising a cone valve, thereby obtaining a depressurized solvent-containing solids stream and vaporizing part of the solvent present in the bed; wherein the solvent-containing solids stream in the vessel in step (b) is at a temperature above the boiling point of the solvent in the depressurized solvent-containing solids stream at the second pressure in step (c).
