Producing metal halides or metal oxide halides from metal-oxygen compounds or metals, comprises (i) generating at least one halogenating reagent which is gaseous at conditions prevailing in step (i), and (ii) reacting the halogenating reagent with the metal-oxygen compounds or metals for converting the metal-oxygen compounds or metals to metal halides or metal oxide halides, discharging the metal halides or metal oxide halides into gaseous aggregation state, and transferring the metal halides or metal oxide halides from the gaseous aggregation state to liquid- or solid aggregation state. Producing metal halides or metal oxide halides from metal-oxygen compounds or metals, comprises (i) generating at least one halogenating reagent which is gaseous at conditions prevailing in step (i), and (ii) reacting the gaseous halogenating reagent with the metal-oxygen compounds or metals for converting the metal-oxygen compounds or metals to metal halides or metal oxide halides, discharging the metal halides or metal oxide halides into gaseous aggregation state from the step (ii), and transferring the metal halides or metal oxide halides from the gaseous aggregation state to liquid- or solid aggregation state or introducing into reverse reaction of its formation. The second reaction step is locally separated from the first reaction step. The step (ii) is followed by the step (i). The halogenating reagent produced in the step (i) is transported to the step (ii) using a gas stream.
