METHOD FOR IMPROVING YIELD OF TITANIUM-RICH MATERIAL FOR BOILING CHLORINATION, AND USE THEREOF

The present disclosure relates to the technical field of metallurgy, and in particular to a method for improving the yield of a titanium-rich material for boiling chlorination, and the use thereof. The method for improving the yield of a titanium-rich material for boiling chlorination comprises: mixing titanium slag with an acid solution for pre-acid leaching, so as to dissolve metal iron out of the titanium slag and, after the pre-acid leaching is completed, to obtain a pre-acid leached mixture; and adding an oxidizing agent to the pre-acid leached mixture, carrying out pressurized acid leaching so as to dissolve an impurity element out of the pre-acid leached mixture, and then carrying out solid-liquid separation to obtain a titanium-rich material for boiling chlorination, the impurity element comprising at least one of a calcium element, a magnesium element, an aluminum element and a manganese element, and the oxidizing agent comprising at least one of a gaseous oxidizing agent, a reactive metallic compoun
