| titleOfInvention | A method for enriching scandium in the process of leaching ilmenite with hydrochloric acid to produce titanium-rich material |
| abstract | The invention discloses a method for enriching scandium in the process of leaching ilmenite with hydrochloric acid to produce titanium-rich material, and belongs to the field of hydrometallurgy. Ferro-titanium material is leached with hydrochloric acid to obtain leachate, which enters the pre-concentrator to concentrate; the concentrated leachate enters the cooling tank for cooling, and then separates FeCl 2 4H 2 O crystals through the filter. The cooling medium of the cooling tank is NaOH reaction Extracting agent; the treated concentrated leachate is extracted with extractant to extract scandium, and the washing liquid prepared by regenerated hydrochloric acid is used to purify the loaded organic phase, and back-extracted with hot NaOH solution, and solids rich in scandium are obtained after solid-liquid separation; the poor solution and FeCl are extracted 2. 4H 2 O crystallization is returned to the incinerator in the titanium-rich material production process; washing waste liquid is returned to the primary absorption tower of the hydrochloric acid recovery system. The present invention rationally utilizes hydrochloric acid leaching ilmenite to produce various intermediate products in the process of producing titanium-rich materials, and the stripping process makes full use of the heat of the concentrated leaching solution, and extracts poor liquid and washing waste liquid to return to the production process of titanium-rich materials, which has great advantages Low material cost and zero discharge of pollutants are realized. |
