Abstract
Manganiferous oxide minerals, particularly sea nodules, containing at least one metal value selected from the group consisting of cobalt, copper, iron, molybdenum and nickel and a reductant are heated to a temperature above about 1100.degree.C. to selectively reduce the metal values to metal and only minor amounts of the manganese values to metal and to coalesce the reduced metal values. The coalesced metal values are recovered by techniques such as magnetic separation, flotation and tabling to produce a concentrate of the metal values.
