摘要
A process for the enrichment of anatase mechanical concentrates, in order to obtain synthetic rutile with low contents of rare earth and radioactive elements, comprising the steps of: calcination of the anatase concentrate; reduction of the calcined product; dry or wet low-intensity magnetic separation of the reduced product; dry, high-intensity, high-gradient magnetic separation of the non-magnetic fraction from the low-intensity separation; leaching of the high-intensity magnetic fraction; oxidation of the dried product; leaching of the quenched product; filtering of the product from the second leaching; drying of the filtered product; and dry, high-intensity, high-gradient magnetic separation of the product of the second leaching.
