Magnetic separation production line is a new type of sorting equipment for coarse size ore sorting. Its working principle is to use the magnetic effect of magnetic substances to separate the materials, so as to achieve the sorting requirements of fine particle size ores. Magnetic separation equipment generally includes wet magnetic separator, dry magnetic separator and other types. Different types of equipment are suitable for different types of ores and production requirements. In addition, the magnetic field strength and magnetic media are also important factors affecting the magnetic separation effect.

Process flow

The mined ore is firstly crushed by the jaw crusher, and after crushing to a reasonable fineness, it is evenly sent to the ball mill through the elevator and feeder, and the ball mill crushes and grinds the ore. After the ball mill grinding, the ore fines enter the next process: classification. The spiral classifier washes and classifies the ore mixture by the principle that the specific gravity of solid particles is different and the speed of sedimentation in liquid is different.

When the washed and graded mineral mixture passes through the magnetic separator, the magnetic materials in the mixture are separated by magnetic and mechanical forces due to the different specific magnetization coefficients of various minerals. After the desired minerals are separated out, because they contain a lot of water, they must be concentrated by the initial concentration of the thickener, and then dried by the dryer to get the dry minerals.

Equipment configuration

The magnetic separation production line consists of vibrating feeder, trough feeder, jaw crusher, vibrating screen, ball mill, classifier, magnetic separator, thickener and dryer and other main equipment, which can form a complete mineral processing production line with feeder, elevator and conveyor. This magnetic separation production line has the advantages of high efficiency, low energy, high processing capacity and reasonable economy.

Application Scenario

The magnetic separation line is suitable for the separation and extraction of ores containing magnetic minerals. Its main application scenarios include but are not limited to.

Extraction of iron ore: Magnetic separation production line is a common process for extracting iron ore. In the magnetic separation process of iron ore, the magnetic materials (such as hematite and magnetite in iron ore) and non-magnetic materials (such as quartz and calcite) are separated out through the action of strong magnetic field, so as to obtain iron-containing concentrate, which is suitable for wet magnetic separation of magnetite, magnetic pyrite, roasted ore, ilmenite and other materials with particle size below 3mm.

Extraction of rare earth ore: Rare earth ore usually contains a variety of rare earth elements and its particle size is small. The magnetic separation production line can separate the useful elements in the rare earth ores through various process steps such as magnetic separation and flotation.

Extraction of tungsten ore, tin ore and other metal minerals: tungsten ore, tin ore and other minerals often contain a high proportion of magnetic minerals. The magnetic separation production line can separate these magnetic minerals to achieve the extraction of these metallic minerals.
