Abstract
The invention discloses a novel technology of zircon sand extraction. The technology comprises the following steps: in the wet processing phase, processing the raw ores by gravity separation equipment (shaking table) so as to remove quartz, feldspar, and mica; subjecting the obtained heavy minerals to fine screening to further remove the residual light minerals; concentrating, dehydrating, drying, and cooling the heavy minerals, delivering the heavy minerals to the dry processing phase to further separate the minerals; wherein the dry processing phase comprises weak magnetic screening, strong magnetic screening, and electrostatic screening, in weak magnetic screening, the magnetite is recycled, in strong magnetic screening, ilmenite and garnet are recycled, finally the monazite, rutile and zircon sand are separated by a high voltage electrostatic concentrating machine; and the separated zircon sand content is increased from 2-8% to 90%. The provided technology has the advantages that the impurities in zircon sand are removed, thus the purity of zircon sand is increased, the radioactive substances in zircon sand are reduced, and the processed zircon sand will not harm the health of people.
Description
Technical field
The present invention relates to a kind of materials processing, belong to industrial chemicals processing technique field.
Background technology
Zircon sand is mainly after acidic rock weathering, and in its parent rock, zircon forms sedimentary deposit along with monazite, ilmenite, rutile, garnet etc. impact on seashore.Usually exist with placer and two kinds, rock ore deposit form at occurring in nature, the content of zircon sand is at about 2-8%, and raw ore needs the content improving zircon sand through Physical Processing screening.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop the novel process of a kind of zircon sand extraction.Raw ore is first at the wet-processing stages removing of gravitational separation equipment shaking table quartz, feldspar, mica; The heavy mineral of gained, through selected, gets rid of remaining light mineral further; After concentrated, dehydration, oven dry, cooling, dry process section is sent to do further sorting again; Dry process section is made up of low intensity magnetic separation, high intensity magnetic separation and electrostatic separation, by the difference of magnetic mineral and electroconductibility, reclaims magnetite by low intensity magnetic separation; By high intensity magnetic separation recovery Pd iron ore, garnet; Finally isolate monazite, rutile and zircon with high-tension electrostatic separation machine, isolated zircon sand content brings up to 90% by 2-8%.
The principle of the invention and beneficial effect: novel process effectively removes the impurity in zircon sand, comprise quartz, feldspar, mica, magnetite, ilmenite, garnet, monazite, rutile, improves the purity of zircon sand; Reduce the material monazite containing radioactive source in zircon sand, make zircon sand meet human health standard.
Accompanying drawing explanation
Fig. 1 is schema of the present invention.
