Ore benefication plant is mainly applied to separate copper, gold, sliver, zinc & lead, maganese ore and other non-ferrous metals and non-metallic minerals.
Iron ore benefication plant flow diagram:
1.Crushing & screening
A vibrating feeder is to evenly feed iron ore into jaw crusher and secondary cone crusher, then use vibrating screen to screened out to meet the particle size for grinding.
Machine list: hopper, vibrating feeder, jaw crusher, cone crusher or hammer crusher(optional)
2.Grinding & Classifying
The ore has relatively high hardness and extremely fine particle size. It adopts two-stage grinding process, which is ball mill combined with a spiral classifier to achieve the required grinding fineness.
Machine list: electromagnetic vibrating feeder or similar, ball mill, sprial classifier
3.Magnetic Separation:
Separation generally adopts permanent magnet drum type magnetic separator.Most magnetite beneficiation plants often adopt coarse-grained dry magnetic separation tailings. For the ultra-lean magnetite ore with a grade below 20.00%, the ultra-fine crushing-wet magnetic separation tailing process can be used before entering the mill. That is to say, the ore is finely crushed to below 5mm-3mm, and then wet magnetic separation and tailing are carried out with a permanent magnetic field magnetic separator.
Machine list: strong magnetic separator,weak magnetci separator, high efficiency screen etc.
4. Tailings treatment:
After obtaining the magnetite concentrate, the tailings must be concentrated and dehydrated. After passing through the dryer, the dried mineral products can be obtained.
Machine list: tailing recovery machine, vacuum filter, rotary dryer etc is optional.
