Abstract
L'invention concerne un procédé d'amélioration chimique de concentrés d'anatase, permettant d'obtenir des concentrés ayant une teneur élevée en TiO2 et des caractéristiques semblables à celles du rutile natureL Le procédé consiste à sulfurer des concentrés d'anatase à faible teneur en TiO2 par de l'hydrogène sulfuré et/ou de l'anhydride sulfureux gazeux dans un four chauffé entre 500 et 1 300 degrés C. Après la sulfuration, le matériau sulfuré est lixivié par l'acide chlorhydrique ou l'acide sulfurique dilués à des concentrations de 10 à 20 % en poids. Après la lixiviation acide, le matériau est soumis à une séparation magnétique à l'état humide. La fraction magnétique obtenue peut être renvoyée dans le four de sulfuration, et la fraction non-magnétique est le concentré d'anatase de qualité supérieure à haute teneur en TiO2 . Les réactifs utilisés dans les opérations de sulfuration et de lixiviation sont recyclés et renvoyés dans le cycle opératoire.The invention relates to a process for the chemical improvement of anatase concentrates, allowing to obtain concentrates having a high content of TiO2 and characteristics similar to those of natural rutile. The process comprises sulfurizing low content of anatase concentrates. in TiO2 by hydrogen sulphide and / or sulfur dioxide gas in an oven heated to between 500 and 1300 degrees C. After sulphurization, the sulphide material is leached with hydrochloric acid or sulfuric acid diluted to concentrations of 10 to 20% by weight. After the acid leaching, the material is subjected to magnetic separation in the wet state. The resulting magnetic fraction can be returned to the sulfurization furnace, and the non-magnetic fraction is the premium anatase concentrate with high TiO2 content. The reagents used in the sulfurization and leaching operations are recycled and returned to the operating cycle.
