Crushing & screening, Grinding & Classifying, Magnetic Separation, Tailings treatment
Iron Ore Processing Plant
The complete iron ore processing plant is composed of four stages: crushing & screening, grinding & classifying, magnetic separation, and tailings treatment.
STAGE 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)
STAGE 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
STAGE 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 magnetic separator, high efficiency screen etc.
STAGE 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.
Iron Ore Beneficiation Process
Magnetite is mostly granular aggregates with strong magnetism and wide distribution. According to the different types of iron-containing minerals, magnetite can be divided into single magnetite and mixed ore.
1. Single magnetite mostly adopts weak magnetic separation process. Polymetallic magnetite and mixed ore usually adopt a combined process of flotation and magnetic separation.
2. Magnetite ore containing a variety of metals: containing silicate or carbonate minerals. It often associated with cobalt pyrite, chalcopyrite and apatite. Generally, the combined process of weak magnetic separation and flotation separation is adopted, that is, iron ore is recovered by weak magnetic separation, and sulfide or apatite is recovered by flotation.
3. In order to obtain high-grade concentrate, the magnetite concentrate can be processed by flotation or shock fine screen. In order to improve the recovery rate, tailings reprocessing and other processes can be considered for further recovery.
