ABSTRACT:
This invention provides a process for selectively removing metal values from ocean floor nodule ore by a two-stage procedure. In the first stage, the ore is leached with an aqueous solution of sulfuric acid or a hydrogen halide to preferentially remove nickel and copper. In the second stage, the ore is leached with a reducing agent to preferentially remove cobalt and manganese. The two leach solutions can then be further treated to separate the individual metal values, e.g., by liquid ion exchange procedures.
