Manganese minerals are weak magnetic minerals and can be recovered by using a strong magnetic separator. Henan Shunzhi mainly adopts magnetic separation technology in manganese mineral beneficiation process, which is divided into two stages: strong magnetic roughing and medium magnetic separation. .
The magnetic separation process of manganese ore is suitable for separating high phosphorus, high silicon and low iron manganese ores.
Strong magnetic roughing
Henan Shunzhi first used a special strong magnetic separator for manganese ore to initially remove impurities in manganese ore. The rougher concentrate was classified by a spiral classifier, and the rougher tailings were directly discharged to the tailings thickener.
Grading
The classified underflow of the classifier is sent to the magnetic separator for selection, and the classified overflow is concentrated by the concentrator.
China Magnetics Featured
The concentrated tailings of China Magnetics are discharged to the tailings thickener, and the concentrated underflow of China Magnetics is merged.
concentrate
The concentrated overflow is used to enter the return water system, and the concentrated underflow is combined with the selected concentrate to become the final selected concentrate.
Large-scale raw ore is continuously sent to jaw crusher for primary crushing through vibrating feeder, and then enters heavy hammer crusher for secondary crushing.
The crushed ore enters the circular vibrating screen for screening. For larger crushed ore, it will be sent back to the hammer crusher again for continuous crushing.
Qualified materials are sent to the ball mill for grinding.
The materials with suitable particle size processed by the ball mill are transported to the magnetic separator for magnetic separation operation.
