Introduction
Manganese minerals are weakly magnetic minerals, which can be recovered by using a strong magnetic separator. Hongji mainly uses magnetic separation process in manganese mineral processing, which can increase the grade of manganese ore by 4% ~ 10% and bring rich benefits to the separation plant.
Process of Manganese Ore Beneficiation
① Strong Magnetic Roughing
We use a special high intensity magnetic separator to remove impurities in manganese ore. The coarse concentrate is graded by spiral classifier, and the coarse tailings are directly discharged to the tailings concentrator.
② Fractionation
Underflow from the classifier is transported to magnetic separator for concentration, the overflow will be concentrated by thickener.
③ Middle Magnetic Separation
The tailings from middle magnetic separation drain to concentrator, the concentrate from middle magnetic separation gets together with underflow of the concentration.
④ Purification and Concentration
Concentration overflow return to system for cycling, concentration underflow gets together with concentrate, to be the final separated concentrate.
