1. Crushing and screening: a vibrating feeder is installed in front of the crusher, and the raw ore is evenly fed into the jaw crusher. Then the raw ore that meets the particle size is screened out by a vibrating screen for crushing.

• For high-grade magnetite, a closed-circuit method is usually used to obtain magnetite with qualified particle size;
• For low-grade magnetite, three-stage open-circuit or three-stage closed-circuit operation is used to complete ore crushing.

2. Grinding and classifying: the ore has high hardness and extremely fine size. The closed-circuit ring grinding process combines ball mill and spiral classifier to achieve the required grinding fineness.

3. Magnetic separation: permanent magnet drum-type magnetic separator is generally used for separation.

Most magnetite concentrators often use coarse-grained dry magnetic separation tailings. The ultra-lean magnetite with a grade below 20.00%, the ultra-fine crushing-wet magnetic separation tailings process can be used before grinding. The ore is finely crushed to below 5mm-3mm, and then wet magnetic separation and tailings are carried out with a permanent magnetic field magnetic separator.

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.
