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.
The fluorinated mica crystals have very good high temperature resistance, corrosion resistance and light transmission properties, and can work for a long time at a high temperature of 1100°C.
No reaction occurs with strong acids and alkalis; complete light transmittance (pure and transparent). The natural mica plates traditionally used in the observation window of high-pressure boiler water level gauge are all brown, and the light transmittance is not good, and the temperature resistance is in the range of 200-700°C, especially the corrosion resistance is poor. The boiler steam drum water in thermal power plants contains alkali. After reacting with natural mica and alkali, it is washed with hot air and hot water, and it is prone to fluffing, scaling, and being broken. In the short term (about 1-2 months), the water level is not clearly understood. After being broken, it can easily cause leakage. The fluorite mica does not react with the acid-base solution, and does not react with water in the hydration reaction, so that it does not form a layer, does not scale, and does not break. In the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained. In China, it has been widely applied to the observation window of steam boiler water level gauge in high-pressure boilers of thermal power plants. It has also been selected by Japanese BBK company and NDK (Colin) company for the observation window of high pressure boiler drum level gauge.
