Beneficiation method for xenotime

The invention provides a beneficiation method for xenotime. The beneficiation method comprises the following steps of obtaining original ore pulp; performing low-intensity magnetic separation on the original ore pulp, and removing mechanical iron to obtain rough ore pulp; performing strong magnetic separation on the rough ore pulp to obtain primary xenotime concentrate and primary xenotime tailing; performing primary scavenging on the primary xenotime tailing to obtain secondary xenotime concentrate and secondary xenotime tailing; performing secondary scavenging on the secondary xenotime tailing to obtain tertiary xenotime concentrate and tertiary xenotime tailing. Compared with gravity separation and electric separation, the beneficiation method for separating and enriching the xenotime by sequentially adopting low-intensity magnetic separation, strong magnetic separation, primary scavenging and secondary scavenging has the advantage that fine minerals can be better recovered; compared with the flotation mode, the beneficiation method has the characteristics that no medicament is needed to be added, equipment is easy to control, and the pollution to the environment is small.
