Example Embodiment
[0024] The method for beneficiating fine-grained magnetic minerals of the present invention sets the slope and speed of the sorting drum based on the components of the mineral material. After the fine-grained mixed mineral material enters the sorting drum, the centrifugal force and spiral magnetic system Under the action of magnetic field force, it is adsorbed on the sorting drum and rotates with it. The non-magnetic and weakly magnetic minerals are washed and separated with rinsing water, and moved to the lower end of the sorting drum to the tailings discharge hopper and discharged. Under the action of the relative movement between the sorting drum and the spiral magnetic system, the minerals move in a spiral shape to the high end of the sorting drum, and after being separated from the magnetic field, they are discharged to the concentrate discharge hopper through the spiral discharge plate and discharged.
