Very high magnetic field intensity 16000gauss - 20000gauss. 2. This separator can separate four different minerals in one time. 3. This separator can get the final concentrate of three to four minerals. 4. Ta & Nb grade can reach 60% by using this separator. 5. It's easy to install, adjust, and operate.

So, the separation efficiency reduces by gravity method due to the lower value of concentration criterion. To address this, dry magnetic separation is an alternative approach to separate these iron-bearing gangue minerals from the chromite. This work investigated on the application of different dry high-intensity magnetic separators to …

The magnetic separator can also be classified as permanent or electromagnet magnetic separator. Magnetic separator for mineral processing industry falls into three basic categories: low, medium and high intensity, based on the relative magnetic field strength employed to accomplish separation. The following magnetic …
