ABSTRACT:
This invention provides a process for separating metal values from an anhydrous mixture of metal halides in a fluid state, i.e. vapor or liquid; the separation is made by contacting a fluid mixture containing a halide of at least one less-noble metal selected from the group consisting of iron and manganese, and a halide of at least one more-noble metal selected from the group consisting of copper, cobalt and nickel, with an elemental metal. This procedure is especially effective in the refining of ocean floor nodule ores.
