The vertical mill has two layers of screens, the upper layer is a bar mill made of angle steel, the mill slit width is 20 mm, and the lower layer is a 20×20 mm square hole mill. The coarse tailings were removed using a Humphrey spiral concentrator.
The coarse concentrate from the heavy separation goes into the flotation process.Three mixing tanks are used before flotation. The first mixing tank is added with or sodium silicate to disperse the slime, and then the sodium carbonate is added to adjust the pH of the slurry to about 10; the second blending tank is added with the fatty amine acetate cation collector to make It interacts with the side of the muscovite and adsorbs it.
The fat in the third blending tank is added with the amine acetate salt cation collector, so that it absorbs with the muscovite layer, and then the foaming agent is added. After a rough selection three times, the mica concentrate is obtained. The mica concentrate has a grade of 98% and a recovery rate of 85%.
