The device includes means connected to said collector for withdrawing hydrothermal fluid from the source and means are provided for concentrating the polymetal compounds thereof by settling or by centrifugation with a pipe for raising the so-concentrated flow to a surface installation associated with a bottom turbine energized by power derived from the hydrothermal fluid energy.
