Multiple product separation method of sea beach placer

Abstract

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.

Description

technical field [0001] The invention relates to a sorting method of seaside placer, and relates to a sorting method of multi-products of seaside placer, especially the placer is rich in useful minerals such as ilmenite, monazite and zircon, and has fine particle size and high specific gravity. Refractory seaside placer with small difference and similar magnetic properties. Background technique [0002] At present, the commonly used process for the production of seaside placer is the gravity separation and electric separation process, that is: the seaside placer raw ore directly enters the spiral chute for re-election twice or more times to obtain the gravity-selected coarse concentrate, which contains titanium grade TiO 2 ≧27%, the main components include ilmenite, monazite, zircon sand and a small amount of quartz ore, and then the gravity-selected rough concentrate is concentrated, dehydrated, dried, and finally selected by electro-separation, and the final electro-separat...

AI Technical Summary

Problems solved by technology

Since the electric separation operation is a dry type mineral separation, its existence requires high ore grade, complicated pre-preparation process, high energy consumption in the drying operation, large dust in dry separation of fine-grained materials, serious environmental pollution, and mutual inclusion of tailings comprehensive products in electric separation. Serious, high production cost, low yield recovery rate, large waste of mineral resources, not conducive to environmental protection and other shortcomings
