Abstract: An improved method for treating manganese-containing materials, such as nodules recovered by undersea mining, including reacting the materials with ammonia, and leaching with a mineral acid, and to methods for recovering valuable constituents from such nodules, especially manganese, cobalt, nickel, iron, copper, titanium, vanadium, cerium, and molybdenum. A method for the production of nitrate products is also disclosed.

Abstract: It is described a manganese pellet production from non-calcinated manganese ore, comprising the following phases: (a) ore size preparation through ore classification by function of particle size, smaller or equal to 1 mm particles being maintained from the ore particle fraction process so as to have a smaller or equal to 1 mm size, as well as the comminution of these particles; (b) flux addition; (c) agglomerant addition; (d) pelletizing resulting in crude pellets; and (e) thermal processing through crude pellet drying, pre-heating and heating.
