Methods are provided for removing fine particles from crude oils extracted from mined oil sands using a non-aqueous extraction solvent. A bitumen derived from non-aqueous extraction of oil from oil sands can undergo optional physical separation to remove larger particles and then processed using electrostatic filtration to remove particle fines. This can allow for production of a bitumen product from a non-aqueous extraction process that has a sufficiently low particle content to be suitable for pipeline transport.
