METHOD OF PRODUCING MANGANESE PELLETS FROM NON-CALCINED MANGANESE ORE AND AGGLOMERATE OBTAINED USING SAID METHOD Russian patent published in 2014 - IPC C22B1/14

Abstract RU 2519690 C2

FIELD: chemistry.

SUBSTANCE: invention relates to production of manganese pellets from non-calcined oxide manganese ore. The method comprises the following steps: (a) ore particle size preparation through ore classification depending on particle size, particles smaller or equal to 1 mm being obtained from the ore particle fraction process and grinding said particles, (b) flux addition; (c) agglomerant addition; (d) pelletising to obtain crude pellets; and (e) thermal processing by drying, pre-heating and heating the crude pellets.

EFFECT: invention enables to obtain pellets having high mechanical strength with greater mass balance precision.
