The invention relates to the technical field of metallurgy, in particular to a method for improving the yield of a titanium-rich material for fluidizing chlorination and application of the method. The method for improving the yield of the titanium-rich material for boiling chlorination comprises the following steps: mixing titanium slag with an acid solution for pre-acid leaching to dissolve out metal iron in the titanium slag, and obtaining a pre-acid-leached mixture after the pre-acid leaching is completed; an oxidizing agent is added into the mixture obtained after pre-acid leaching, pressurized acid leaching is conducted, impurity elements in the mixture obtained after pre-acid leaching are dissolved out, then solid-liquid separation is conducted, and the titanium-rich material for boiling chlorination is obtained; the impurity elements comprise at least one of calcium element, magnesium element, aluminum element and manganese element; the oxidizing agent comprises at least one of a gaseous oxidizing agen
