Abstract
A method of recovering metal values from deep sea manganese nodules. A liquid reductant such as bunker-C oil is utilized as a reducing agent. As a result of the efficient contact between the liquid reducing agent and the nodules, little prior preparation of the nodules is required to recover a high percentage of copper, nickel, cobalt and molybdenum. A new series of metal alloys are produced in the selective reduction of the nodules, the major phase being iron-rich nickel, one minor phase being 80-90% copper and the other minor phase being a combination of manganese, molybdenum, nickel, cobalt and iron.
