In order to solve the problem of increasing the difficulty of sorting lead-zinc tailings in China, the re-separation of lead-zinc tailings is realized, the recovery efficiency is improved, and the sorting cost is reduced. Through the structural improvement of the traditional column conical cyclone, a spiral wall cyclone suitable for secondary sorting of lead-zinc tailings is proposed, and the lead-zinc tailings with different density are quickly separated by using the diversion of the spiral wall and the enrichment of mineral particles. The results showed that the recovery rate of heavy concentrate PbO increased from 55.55% to 85.25% by the spiral wall cyclone after structural optimization, an increase of nearly 30%, and the enrichment ratio of down-export PbO concentrate also increased from 1.321 to 1.762. It can be seen that the optimized spiral wall cyclone can effectively increase the secondary sorting efficiency of lead-zinc tailings, and provide a reference for the structural design of hydraulic cyclones in the same type of mine to a certain extent.
