Tantalum-niobium ore, as a rare metal mineral, is often associated with elements such as lithium, beryllium, and tin.  The mineral density is generally higher than that of ordinary gangue (tantalum-niobium ore density is approximately 6-8 g/cm³, while gangue density is mostly 2.5-3.5 g/cm³).

The first step in ore processing is crushing the mined tantalum-niobium ore to reduce its particle size to a size suitable for subsequent beneficiation operations. Jaw crushers are generally used for coarse crushing, followed by cone crushers for intermediate crushing.

Dry Magnetic Separation: After crushing, the tantalum-niobium ore enters a dry magnetic separator. In this process, due to the different forces exerted on magnetic and non-magnetic minerals in the magnetic field, magnetic minerals are adsorbed onto the drum or conveyor belt of the magnetic separator, while non-magnetic minerals are thrown out, thus achieving preliminary separation.

Refining and Purification: The preliminary concentrate obtained after dry magnetic separation is further refined. This process may involve the use of vibrating screens and other equipment to further screen and remove impurities, improving the grade of the tantalum-niobium concentrate.
