Manganese ore processing line

Process Description

• 01

  Crushing and Screening.

  The large manganese ore is sent to the jaw crusher by the vibrating feeder through the silo for coarse crushing; the coarsely crushed manganese ore is screened by the vibrating screen and sent to the single-cylinder hydraulic cone crusher by the belt conveyor for medium crushing; the manganese ore after medium crushing is sent to the multi-cylinder hydraulic cone crusher for fine crushing.

• 02

  Dry throwing.

  The crushed manganese ore is sent to the permanent magnetic drum magnetic separator for preliminary magnetic separation, the concentrate enters the next process, the tailings enter the permanent magnetic high-field strength roller magnetic separator for secondary magnetic separation, the tailings are discarded, and the concentrate enters the next stage.

• 03

  Grinding. 

  After dry throwing, the manganese ore is evenly fed into the mill for grinding, and then the slurry pump pumps the ore slurry into the first cyclone for coarse and fine separation. The fine material overflows into the next process, and the coarse material enters the second mill. After being ground by the second mill, it enters the second cyclone for coarse and fine separation. Similarly, the fine material enters the next process, and the coarse material returns to the second mill to form a closed loop.

• 04

  Ore dressing.

  The manganese ore powder with the required particle size is sent to the wet permanent magnetic separator for medium magnetic separation to remove the mechanical iron in the slurry, and then enters the vibrating safety screen to prevent large materials from entering the next process section. The slurry is then driven into the high-gradient vertical ring magnetic separator for strong magnetic sweeping to separate the manganese ore powder from the tailings to obtain manganese concentrate slurry, which is then driven into the manganese ore thickening tank. The tailings then enter the second-stage high-gradient vertical ring magnetic separator for secondary strong magnetic sweeping to obtain swept manganese concentrate. The manganese concentrate slurry is also driven into the thickening tank for preliminary concentration and dehydration, and then enters the disc filter to separate the concentrate from water. The dehydrated manganese concentrate is transported to the finished product warehouse; the tailings after sweeping enter the tailings thickening tank, and after concentration, they enter the disc filter for mud and water separation. The filter dehydrates the mud and enters the stockpile.
