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. A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.

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