Process for selectively recovering metal chlorides from a gaseous mixture of metal chlorides by contacting the gaseous mixture at a temperature above the condensation point of the mixture with at least one stream of liquid to cool all the mixture to below the freezing point of at least one metal chloride in the mixture, the average velocity of the mixture being at least the pneumatic conveyance velocity at the point of contact. This process provides for recovery of metal chlorides without plugging the apparatus.
