The present invention provides an apparatus (10j) and method for separating different chemical species from each other when they are suspended or entrained in liquid metal as solid particles. The apparatus (10j) comprises a vessel (2) for containing liquid metal. The vessel (2) is continuously axially symmetric about a longitudinal axis (Z), and at least part of it tapers to an apex. The vessel (2) comprises an inlet (4) for the liquid metal having suspended or entrained therein, particles of a plurality of different chemical species of respectively different densities each in solid phase, an underflow outlet (5) for the liquid metal with a majority of particles of a first, denser one of the plurality of different chemical species suspended or entrained therein, and an overflow outlet (6) for the liquid metal with a majority of particles of a second, less dense one of the plurality of different chemical species suspended or entrained therein. The underflow outlet (5) is nearer to the apex of the vessel (2) than the overflow outlet (6). The apparatus (10j) also comprises a first electrode (12) coaxial with the longitudinal axis (Z) of the vessel (2), one or more second electrodes (14) spaced apart from the first electrode (12), and a source (17) of a magnetic field. The first and one or more second electrodes (12, 14) each have a magnetic susceptibility with an absolute value of less than 10-2 to avoid disturbing the magnetic field. They are arranged within the vessel (2) to be immersed in the liquid metal when the vessel (2) contains the same, thereby allowing an electrical current (I) to flow through the liquid metal between the first and one or more second electrodes (12, 14). The magnetic field has a major component which is substantially perpendicular to the flow of electrical current (I) through the liquid metal between the first and one or more second electrodes (12, 14). This generates a Lorentz force acting on the liquid metal, causing it to rotate around the longitudinal axis (Z) of the vessel (2). The method may be conducted using such an apparatus. The speed of rotation of the liquid metal is varied by altering the Lorentz force acting on it until the liquid metal forms a vortex inside the vessel (2), which separates the particles of the different chemical species from each other and directs them to a respective one of the underflow or overflow outlets according to their different densities. If the different chemical species also have different magnetic susceptibilities from each other, the magnetic field can act directly on the particles as well in different manners according to their different susceptibilities, thus enhancing their separation according to their different densities. For example, the liquid metal may comprise liquid sodium and the solid particles may comprise the insoluble reaction products from a redox reaction between the liquid sodium and an ore of iron and / or of manganese, in which the liquid sodium acts on the ore as a chemical reducing agent and excess unreacted liquid sodium acts as a transport medium for the insoluble reaction products.
