The floatability of manganese minerals

Manganese Mineral two types: one is an oxide; the other is a carbonate. The floatability of important manganese minerals is as follows:

Manganese ore MnC03, containing 47.8% Mn, is a relatively easy to float mineral in manganese ore. Collectors are commonly used in fatty acids, of which oleic acid works best. The most suitable pH for flotation is 8-9. Medium adjuster is commonly used sodium carbonate. Water glass can be used to inhibit quartz gangue, but the alkalinity is too high or the amount of water glass is too large, which has an inhibitory effect on rhodochrosite.

Pyrolusite MrS2, containing Mn63.2%, is less difficult to float than rhodochrosite, and the collector uses fatty acids during flotation. The pH adjuster is sodium carbonate. Gangue inhibitor water glass. Dextrin and citric acid are inhibitors of manganese oxide ore. Oxalic acid activates it. The test proves that in the flotation of manganese oxide ore, it is collected by oleic acid. Under the condition of pH 6.5, the manganese ore and the manganite are relatively easy to float, while the soft manganese ore and hard manganese ore are the most difficult to float. Only when tartaric acid and water glass are used to disperse the slime can a satisfactory result be obtained. When there is mud, the flotation effect is poor. Desliming the ore, such as removing 10μμ of slime, can improve the flotation index.
