Application and implementation:
in the flotation tailings, manganese concentrate is magnetically separated by a high-gradient magnetic separator in a certain lead-zinc sulfide ore dressing plant. Manganese concentrate enters a thickening hopper 1 for thickening after magnetic separation, the thickening hopper 1 overflows into a filling system for filling, and bottom flow products of the thickening hopper 1 enter a ceramic filter for filtering. Because the manganese concentrate particles generated by magnetic elutriation of the high-gradient magnetic separator and washing of water are relatively coarse in the production process, the manganese concentrate particles are easy to settle.
