All refrences to claim(s) which appear below refer to the numbering after this setence.

1. A solid separator for separating solid particles from a mixture containing the particles and a liquid, the solid separator comprising:
a collecting vessel adapted to receive at a filling position the mixture containing the particles and the liquid, wherein the liquid does not drain out of the collecting vessel at the filling position, the collecting vessel having an impermeable bottom wall, being mounted in at least one bearing such as to be rotatable about an axis of rotation, and being rotatable from the filling position to a liquid run-off position where the liquid is able to be at least partially drained out of the collecting vessel, and wherein the collecting vessel is adapted to be moveable from at least one of the liquid run-off position and the filling position to a solid discharge position;
a device for producing a magnetic field to at least partially retain the particles in the collecting vessel at the liquid run-off position; and
a solid-holding container disposed below the collecting vessel for receiving the solid matter discharged from the collecting vessel.
2. The solid separator of claim 1, wherein the collecting vessel is rotatable from at least one of the liquid run-off position and the filling position into the solid discharge position.
3. The solid separator of claim 1, wherein separated solid matter is dischargeable from the collecting vessel at the solid discharge position by the effects of gravitational force.
4. The solid separator of claim 1, wherein the device for producing a magnetic field comprises at least one fixed magnet element.
5. The solid separator of claim 1, wherein the device for producing the magnetic field comprises at least one permanent magnet element.
6. The solid separator of claim 1, wherein the collecting vessel is formed from a non-magnetic material.
7. The solid separator of claim 1, further comprising a heating device for heating the collecting vessel.
8. The solid separator of claim 7, wherein the heating device is fixed.
9. The solid separator of claim 7, wherein the collecting vessel comprises at least one side wall which is adjacent to the heating device in each position of the collecting vessel.
10. The solid separator of claim 7, wherein the heating device comprises a heat exchanger.
11. A liquid medium processing plant, comprising:
at least one solid separator with a collecting vessel adapted to receive at a filling position a liquid medium containing solid particles and a liquid, the collecting vessel being movable from the filling position to a liquid run-off position where the liquid is able to be at least partially drained out of the collecting vessel;
a device for producing a magnetic field to at least partially retain the particles in the collecting vessel at the liquid run-off position; and
at least one vaporizing device for at least partially vaporizing the liquid that has drained out of the solid separator.
12. The liquid medium processing plant of claim 11, wherein the solid separator comprises a heat exchanger and vapour from the vaporizing device is supplied at least partially to the heat exchanger.
13. The liquid medium processing plant of claim 11 further comprising at least one magnetic separator to increase the concentration of solid particles in the liquid medium being processed.
14. A solid separator for separating solid particles from a mixture containing the particles and a liquid, the solid separator comprising:
a collecting vessel adapted to receive at a filling position the mixture containing the particles and the liquid, the collecting vessel being movable from the filling position to a liquid run-off position where the liquid is able to be at least partially drained out of the collecting vessel,
a heating device for heating the collecting vessel, wherein the heating device comprises a heat exchanger comprising a vapour flowing therethrough; and
a device for producing a magnetic field to at least partially retain the particles in the collecting vessel at the liquid run-off position.
15. A solid separator for separating solid particles from a mixture containing the particles and a liquid, the solid separator comprising:
a collecting vessel adapted to receive at a filling position the mixture containing the particles and the liquid, the collecting vessel being movable from the filling position to a liquid run-off position where the liquid is able to be at least partially drained out of the collecting vessel, the collection vessel further comprising:
a run-off wall along which the liquid drains out of the collecting vessel in the liquid run-off position; and
a wall disposed opposite the run-off wall, whereby, in the filling position of the collecting vessel, an average gradient of the run-off wall is less than an average gradient of the wall opposite the run-off wall; and

a device for producing a magnetic field to at least partially retain the particles in the collecting vessel at the liquid run-off position.
16. The solid separator of claim 15, further comprising a gutter wall aligned transversely relative to the run-off wall and arranged on an edge of the run-off wall.
