Three Disc Magnetic Separator for Tantalum, Niobium & Rare Metal Ore
A three disc magnetic separator is a high-intensity dry magnetic separation machine used for the purification of weakly magnetic and rare metal ores. First of all, it features three independent rotating magnetic disks, each with an adjustable magnetic field strength. Unlike wet magnetic separators, it operates without water, making it ideal for arid mining areas and water-sensitive materials. Therefore, it is widely used as the final purification stage for tantalum–niobium, tin, tungsten, ilmenite, and monazite concentrates.

Key Features of Our Three Disc Magnetic Separator
Our three disc magnetic separator is designed for precision, durability, and ease of operation:
Three Independent Magnetic Disks: Each disk can be adjusted independently, allowing for precise separation of minerals with different magnetic susceptibilities.
High Magnetic Intensity: Adjustable from 0 to 20,000 Gauss, suitable for both strongly magnetic and weakly magnetic minerals.
Dry Operation: No water required, making it perfect for arid mining areas and water-sensitive materials.
Compact Structure: Small footprint, easy to integrate into existing production lines.
Simple Maintenance: The belt is the main wear part and can be easily replaced, reducing downtime.
Wide Applications of Our Three Disc Magnetic Separator
Our three disc magnetic separator is widely used for the dry separation and purification of various minerals:
Tantalum-Niobium Ore: Final purification to achieve high-grade Ta-Nb concentrate.
Tin & Tungsten Ore: Separation of cassiterite and wolframite from associated minerals.
Ilmenite & Monazite: Recovery of titanium and rare earth minerals.
Zircon & Rutile: Purification of heavy mineral sands.
Non-Metallic Minerals: Iron removal from quartz, feldspar, and kaolin.
Technical data
Our three disc magnetic separators are available in two main models. Key parameters include:
| Model | Magnetic Intensity (Gauss) | Number of Disks | Disk Diameter (mm) | Feed Size (mm) | Capacity (kg/h) | Motor Power (kW) |
|---|---|---|---|---|---|---|
| 3PC-500 | 0–18,000 (Adjustable) | 3 | 500 | ≤2 | 100–300 | 0.75 |
| 3PC-600 | 0–20,000 (Adjustable) | 3 | 600 | ≤2 | 200–500 | 1.5 |
Working Principle: How Does It Separate Minerals?
The three disc magnetic separator operates on a precise magnetic difference principle:
Vibrating Feeder Distribution: The dried mineral mixture is fed evenly onto a conveyor belt through a vibrating feeder.
Three-Stage Magnetic Sorting: As the material passes beneath the three rotating disks, each disk generates a magnetic field of different intensity. First of all, the first disk captures strongly magnetic particles. Subsequently, the second and third disks capture weakly magnetic particles of different susceptibilities.
Adjustable Field Strength: The magnetic intensity of each disk can be individually adjusted by changing the excitation current or the distance between the disk and the belt. Consequently, up to four different minerals can be separated in a single pass.
Discharge: Magnetic particles are carried by the rotating disks and discharged into separate collection chutes, while non-magnetic particles continue along the belt and are discharged at the tail end.
Frequently Asked Questions
Q: What is the difference between a three disc magnetic separator and a wet magnetic separator?
A: A three disc magnetic separator is a dry high-intensity magnetic separator, suitable for water-scarce areas and fine weakly magnetic minerals. A wet magnetic separator uses water as a medium and is typically used for strongly magnetic minerals like magnetite.
Q: How many minerals can it separate in one pass?
A: By adjusting the magnetic intensity of each disk, it can separate up to four different minerals in a single pass, including strongly magnetic, weakly magnetic, and non-magnetic fractions.
Q: What is the maximum magnetic intensity?
A: Our 3PC-600 model can reach up to 20,000 Gauss, which is sufficient for most weakly magnetic rare metal ores.
Q: Is the belt a wear part?
A: Yes. The conveyor belt is the main wear part. It can be easily replaced, and we supply spare belts for long-term operation.
