1. Crushing and grinding process
Magnetite ore is transferred through a plate from a vibrating feeder into a jaw crusher. It is then sent into a fine ore storage and conveyed to a ball mill where the ore must be ground to meet size requirements. The ore which has been processed by a vibrating screen can be divided into coarse powder materials and fine materials. Fine size materials are fed into a strong magnetic separator to remove a large number of gangue minerals, and the subsequent magnetic concentrate is mixed with the sieve and conveyed into an overflow-type ball mill. Then, we use the overflow ball mill and a slurry separator for the processing of tailing. Ore concentrates are pumped into the cyclone for classification purpose. The overflow is piped into the magnetic separation stage and the underflow is sent back to the ball mill for re-circulating.
2. Magnetic separation process
Magnetic separation is the key process of the entire magnetite beneficiation process. Magnetic effect is a direct impact on the final concentrate grade. Magnetite beneficiation process uses three segments magnetic separation technology. Beneficiation equipment sets are magnetic separator, plastic pump and ceramic filter. Cyclone overflow is piped into the rougher magnetic separator, and the rougher-scavenger tailings are sent into the magnetic separator. These tailings are treated to form the desired concentrate. Concentrate is transferred through the gum into the ceramic filter dewatering pump. Then we get dry concentrate, and run the water through a gas-water separator system.
3. Dry tailings discharge
Dry tailings discharge is an important part of the magnetite beneficiation process. The main tailings dry exhaust equipment sets are efficient thickener, cyclone and efficient multi-frequency sieve dehydrator.
Magnetite has a wide variety of uses. Right from serving as a magnetic decor for your refrigerator door, to keeping trains from moving off tracks, magnetite uses have a wide range that span across domestic as well as heavy industrial purposes.
However, the most significant use of magnetite lies in its status as an ore of iron and its industrial importance in manufacturing steel. Magnetite is an important material component of power plants as it is used to generate electricity.
Magnetite, owing to its magnetic properties, is widely used in compasses and other navigation devices. Magnetite also serves as an excellent abrasive which is a cleaner and has a lower toxicity than abrasives that have a silica base.
