NOVELTY - The method involves receiving geothermal fluid into a vessel i.e. heat exchanger (12), at a geothermal electrical production facility. Condensate is collected from the fluid. Centrifugal and magnetic forces are applied to the condensate to segregate an element from other components of the condensate. The segregated element is collected from the condensate and removed from the vessel. A sample of the fluid is analyzed to identify the element or another element before applying the forces, where the sample is sent through a measuring instrument e.g. mass spectrometer and chromatograph device.    USE - Method for extracting an element e.g. rare earth element (REE), heavy metal (HE), lanthanide and actinide (all claimed), from hydrothermal product e.g. hot liquid and gas, from underground of a geothermal power plant.    ADVANTAGE - The method enables a drum to be mounted vertically and a magnet to be placed in the center and the drum to spin using the centrifugal force to force the REE and HE to the outside wall of the drum through centrifugal force, which is more controllable than pure normal gravity, so that differing masses of the REEs and HE and differing paramagnetic properties of the REE and HE are obtained, thus enhancing separation process by varying the speed of rotation and the magnetic field. The method enables dust, which is in low density compared to the REE and HE, to be attracted to the magnet, thus eliminating the need to clean the dust during solid extractions, and hence reducing cost.    DETAILED DESCRIPTION - The magnetic force is applied by an electromagnet, and the centrifugal force is applied by a centrifuge. An INDEPENDENT CLAIM is also included for a system for extracting elements from a hydrothermal fluid, comprising a heat exchanger vessel.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a system for utilizing geothermal hot water and steam in a geothermal electric generation plant to co-produce REE and HE.
