FIELD: metallurgy. n SUBSTANCE: method includes materials reacting with ammonia and leaching using mineral acid. The method also includes recovery of valuable components from such nodules, in particular manganese, cobalt, nickel, iron, copper, titanium, vanadium, cerium and molybdenum. In this case, nitrate products are produced. n EFFECT: extraction of manganese-containing materials such as manganese nodules, not only manganese, but also other valuable metals. n 18 cl, 1 dwg |
