PROCESS TO PRODUCE MANGANESE PELLETS FROM NON-CALCINATED MANGANESE ORE AND AGGLOMERATE OBTAINED BY THIS PROCESS |
摘要 |
<p>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.</p> |
