Abstract: A method for recovering base metal values from oxide ore is provided by the present disclosure. The ore includes a first metal selected from the group consisting at least one of iron and aluminum and a second metal selected from the group consisting of at least one of nickel, cobalt and copper. The method includes the steps of: contacting the oxide ore with hydrogen chloride gas to obtain chlorides of the first and second metals and subjecting at least the first and second metals to pyrohydrolysis at a predetermined temperature to decompose the chlorides of the first metal into oxides. The method also includes the step of mixing the oxides of the first metal and the chlorides of the second metal in an aqueous solution to dissolve the chlorides of the second metal and recovering the dissolved ions of the second metal from the aqueous solution.
