How to Process Copper Ore: Beneficiation Methods and Equipment
Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

The hand selection method is a sorting method based on the difference in color and appearance between lithium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral …
Spiral Classifier
Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
