Manganese Oxide Ore Dressing Technology Process Selection

Artificial hand-selected sorting method is employed. Since the manganese ore and gangue significant difference in color, visually easier to distinguish.

In order to improve the grade of mineral hand, hand-selected for sorting oxide ores by the jig. The resulting concentrate grade manganese mineral have greatly improved hand over, grade is relatively stable, but the high side tailings, the recovery is low. Thus, It is imperative to improve the quality and recovery rate of manganese concentrate by better sorting method.

Since the specific magnetic susceptibility of manganese minerals is high, the content of manganese has a good linear relationship with the specific magnetic susceptibility; while the specific magnetic susceptibility of gangue mineral quartz , calcite , dolomite, etc. is extremely low, so manganese is treated with a strong magnetic machine. The ore is expected to have a good sorting effect.

Several beneficiation processes:

Hand selection

Hand selection - jigging

Hand selection - jigging - strong magnetic selection

Hand selection - strong magnetic selection.

Which type of technical route should be selected should be based on the nature of the ore, the characteristics of the mine, and the use of resources to improve the efficiency of selection and market efficiency.
