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.

Abstract: Method to increase the adherence of coating materials on ferrous materials, comprising the step of: before the reduction of iron ores and/or on the agglomerates thereof, contacting same with a dispersion containing at least a particulate material, thus forming a composite coating of at least a material that cannot be substantially hardened in the aqueous mean and at least a material that can be hardened in the aqueous mean.
