The invention relates to a method using a reciprocating sieve plate column to extract and purify native uranium, and the method belongs to the field of extraction. When a pulsed sieve-plate column carries out the extraction and the purification of the native uranium, the energy dissipation is big, the impulse action for feed liquid is not easy to be uniform, and the input and the operation of energy are more difficult. The method has the steps that: when the top interface operation is made and the continuous water phase is adopted, materials are charged towards the reciprocating sieve plate column from an inlet of a water phase, and when a column body which contains a sieve plate series, the water phase stops feeding; a driving device is started, and the vibration frequency is regulated to 80 to 240 per minute according to an organic phase; the flow ratio of the water phase ranges from 1.5 to 3, and an extracting agent is charged towards the column from an inlet of the organic phase; when an interface is established, the rafinate is discharged form an outlet of the water phase through a lower bellend; after the extracting agent of the organic phase begins to pass through an upper bellend to overflow from an outlet of the organic phase, the feeding and the discharging holes of the organic phase and the water phase are respectively provided with the extracting agent and materials to pass in and out according to the flow ratio, and the sieve plate series vibrates. The method has the advantages of simple equipment, stable operation, large flooding loading and low energy consumption.
