The mined titanium-zirconium sand is first processed through a trommel screen. The trommel screen effectively removes oversized gravel and washes away impurities such as soil adhering to the ore surface, preparing the material for subsequent beneficiation steps.
The screened fine-grained sand is transported to spiral chutes. Under the combined action of gravity and water flow, denser valuable minerals (e.g., ilmenite, zircon) settle and concentrate along the inner edge of the spiral chute, while lighter gangue minerals are carried to the outer edge and discharged, achieving preliminary rough concentration.
The rough concentrate obtained from the spiral chutes is further processed on a shaking table for refinement. Through the asymmetric reciprocating motion of the shaking table and the washing action of water flow, denser valuable minerals concentrate at the concentrate end, while lighter gangue minerals such as silica sand are washed away, thereby improving the concentrate grade.
The concentrate obtained from the shaking table contains a significant amount of moisture and needs to be dehydrated and dried using a dryer to meet the requirements for subsequent dry separation processes like magnetic and electrostatic separation.
The dried concentrate is fed into a three-disc belt magnetic separator for magnetic separation. By adjusting the intensity of the magnetic field, strongly magnetic iron impurities can be removed first, followed by the separation of weakly magnetic minerals such as tantalite-niobite, achieving effective separation of magnetic minerals.
For non-magnetic minerals with significant differences in conductivity (e.g., cassiterite and zircon), a high-voltage electrostatic separator is used. Leveraging their different conductive properties in a high-voltage electric field, efficient separation of cassiterite and zircon can be achieved.
The above outlines the common beneficiation process for titanium-zirconium sand.
