Magnetic Separation Process

Detailed description

The magnetic separator is not only suitable for extracting iron ore from magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size below 3mm, but also used to remove the iron ore from coal, non-metallic minerals, building materials, etc.

The magnetic separation process includes dry magnetic separation and wet magnetic separation. Generally, iron ore with an iron content of 35% can increase iron content by 20% after magnetic separation. Such a combined process method, the ore utilization rate can reach 90%.

In the process of magnetic separation, it saves water, reduces cost and pollution. FTM Machinery will provide the dust removal device to help customers control the dust that generates during the magnetic separation.

Magnetic separation process

The whole magnetic separation has two steps to grind the mineral, which avoids the phenomenon of ore muddy caused by mineral over-grinding, but also improve the production capacity and reach the required grinding fineness.

1.Crushing and screening: Using the jaw crusher to crush the large size of iron ore firstly. Then, the broken iron ore will be screened by the screen and be delivered to the ball mill.

2.Grinding: The broken iron ore is delivered to the ball mill to be ground.

3.Magnetic separating: Generally, FTM company uses three magnetic separators for two-stage selection. The first stage uses one magnetic separator for roughly selecting. And the second stage uses two magnetic separators for further selecting, of which one is used for roughly selecting first and the second one is used for carefully selecting.

Then, minerals separated by the magnetic separator will be sent to the flotation machine. According to the different properties of minerals, the different pharmacy will be added into the flotation machine. And this will separate the iron ore from other minerals.

4.Drying: Since the mineral after flotation contains a large amount of water, it must be concentrated by a concentrator and then dried by a dryer to obtain the dry mineral.
