Multiple product separation method of sea beach placer

The invention discloses a multiple product separation method of a sea beach placer, which comprises the following steps: firstly, the roughing integrated concentrate is obtained through the spiral chute re-separation, then, the sectional fine separation of a SLon magnetic separator is adopted for replacing the electronic separation, the sectional section of magnetic separation and fine separation is adopted, meanwhile, high-pulsation fluid force fields and medium width magnetic media are assisted in the magnetic separation process for twice fine separation to separate high-quality titanium concentrate, and the titanium-containing grade TiO2 is greater than or equal to 47 percent; and tailings after ilmenite fine separation are subjected to twice fine separation of high-intensity and large-width magnetic media to respectively separate out monazite, and the final tailings are zircon sand, so the goal of effectively separating the ilmenite, the monazite and the zircon sand is reached. The sectional fine separation of the SLon magnetic separator is adopted for replacing the electronic separation, the problems in the electronic separation flow process are solved, and the separation method has the advantages that the ilmenite, the monazite and the zircon sand can be effectively separated, the production flow process is simple, the field operation implementation is easy, the environment pollution is avoided, and the production cost is low.
