Small Scale Magnetite Processing Line

Magnetite is the main material for iron making and also a kind of traditional medicine. It is formed by the metamorphism of sedimentary rock that contains iron. Magnetite is widely produced in Russia, South America, Brazil, Australia and China etc. Most of the magnetite mines are in large scale, but the grade is low. In order to make full use of it and to upgrade it, we need magnetite processing machine. Here we focus on small scale magnetite processing line.

Small Scale Magnetite Processing Line

A complete magnetite processing line may include crushing stage, grinding stage and beneficiation stage.

Crushing Stage

In the crushing stage, we need a primary crusher and a secondary or fine crusher. Since the Mohs’ hardness of magnetite is about 5.5-6, so we suggest jaw crusher as the primary crusher and cone crusher as the secondary crusher. Jaw crusher is used to crush bulk magnetite into smaller ones. Cone crusher is used to crush the magnetite into small particles suitable to enter the grinding mill. We have various models of jaw crushers and cone crushers, our engineer will recommend suitable model according to the requirements of the customer.

Grinding Stage

Before grinding, we need to use a vibrating screen to grade the magnetite particles discharged from the cone crusher and separate the big particles out. And then the big particles will be sent back to cone crusher for re-crushing. The suitable particles will be ground in the grinding mill into powder. SBM can provide various types and models of grinding mills for the customers, such as ball mill, vertical mill, and trapezium mill and so on.

Beneficiation Stage

As we know, magnetic is kind of strong magnetic minerals, so we suggest our CT series wet magnetic separator. This wet magnetic separator is commonly used for separating strong magnetic materials like magnetite, titan magnetite and so on. It is widely applied in magnetically separating magnetite, de-watering and de-ironing for non-metallic ores. Generally, after separation, the grade of ore can increase 10-30%.
