Methods and apparatuses for separating metal values, such as nickel and nickel compounds, from mineral ores, including lateritic ores are disclosed. The method includes providing a mixture of particles (e.g., crushed and sized ore) that is composed of at least a first group of particles and a second group of particles. Group members have similar chemical composition, while particles belonging to different groups have dissimilar chemical compositions. The mixture of particles is concurrently, or generally concurrently, heated (using microwave/millimeter wave energy) and exposed to a reactant. The wave energy and the reactant act to increase the difference in either the magnetic susceptibility or other separation properties between the first and second group of particles. The mixture of particles is then passed through an appropriate separator to separate the particles of interest. Optional steps are disclosed for purifying selected particles. The reactant includes sulfur, sulfur compounds, halogens, or halogen compounds.

1. An apparatus for separating components of a mixture of particles, the apparatus comprising: a vessel having an interior for containing the mixture of particles during processing,an energy system coupled to and disposed within the vessel for directly exposing the mixture of particles within the interior of the vessel to microwave/millimeter wave energy,a reactant system for exposing the mixture of particles to a reactant,a separator for separating particles, wherein the separator includes a first portion arranged within the interior of the vessel, anda second portion arranged exterior of the vessel, wherein the first portion includes a magnetic separator for diverting magnetic particles away from non-magnetic particles, wherein the second portion includesa first exterior separator portion, anda second exterior separator portion, wherein the first exterior separator portion includes a leach cycle, wherein the second exterior separator portion includes a flotation separator, wherein the flotation separator separates the magnetic particles into a first group of particles and a second group of particles, wherein the first group of particles are passed to a first leach cycle of the second exterior portion, wherein the second group of particles are passed to a second leach cycle of the second exterior portion. 2. The apparatus of claim 1, further comprising a gas distributor for contacting the mixture of particles with said reactant. 3. The apparatus of claim 1, further comprising a gas distributor for distributing said reactant while simultaneously fluidizing the mixture of particles using said reactant. 4. The apparatus of claim 1, wherein said energy system includes a gyrotron ora millimeter wave source. 5. The apparatus of claim 1, wherein said reactant system includes a source of at least one of a sulfur,a compound containing sulfur,a halogen containing chlorine or fluorine,a compound containing halogen, ora hydrogen gas. 6. The apparatus of claim 1, wherein said vessel is open to atmospheric pressure. 7. The apparatus of claim 1, wherein said vessel is closed to atmospheric pressure and said vessel is operated at a pressure that is greater than atmospheric pressure. 8. The apparatus of claim 1, further comprising: a conduit having a first end and a second end, wherein the first end of the conduit is connected to the vessel; anda dust separator, wherein the second end of the conduit is connected to the duster separator, wherein the conduit channels a gas stream from within the vessel into the dust separator, wherein the dust separator removes entrained solids from the gas stream.
