Claim:
A process for mixing a liquid or mixture of a liquid and a fine solid present in an essentially self-contained storage tank, the process comprising: supplying essentially the same liquid or mixture into the storage tank as a stream that flows into a jet nozzle that is disposed in the liquid or mixture; wherein: the storage tank has an internal volume V, the liquid or mixture fills only part of the internal volume V, and a remainder of the internal volume V is occupied by a gas phase; the jet nozzle comprises a motive nozzle and a momentum exchange chamber into which the stream flows after leaving the motive nozzle and before entering a remainder of the storage tank; a suction region of the jet nozzle, where the motive nozzle directs the liquid or mixture into the momentum exchange chamber, is provided with a sheath having at least one suction orifice; the at least one suction orifice is provided below the stream as the stream passes through the jet nozzle; and passage of the stream out of the motive nozzle and into the momentum exchange chamber causes the liquid or the mixture stored in the storage tank to be drawn into the at least one suction orifice.
