ABSTRACT:
In the oxidation of a molten salt, such as copper chlorides with the simultaneous recovery of chlorine values, as chlorine and/or hydrogen chloride, oxygen is introduced into a lower bed and chlorine values are introduced into an upper bed for contact with downwardly flowing melt. By reversing the point of introduction of chlorine values and oxygen, the overall bed contact area required is increased.
