ABSTRACT:
This invention provides a process for obtaining the nonferrous metal values from a manganese oxide ore, by reacting the ore with an aluminum halide or a ferric halide at a temperature of at least about 50.degree. C and preferably, at least about 130.degree. C. The manganese oxide ore can be treated with or without reduction. If reduction of the manganese oxide ore is desired, it can be accomplished prior to, or simultaneously with, the reaction with the aluminum halide or ferric halide.
The resulting nonferrous metal halides can be separated from the reacted ore residue by conventional methods such as leaching or evaporation.
