The invention provides a method for producing a titanium-rich material through ilmenite concentrate. The method includes the following steps of agitation leaching, centrifugal separation and cooling crystallization. The method has the beneficial effects that the technological process is simple, adopted equipment is common equipment, the energy consumption in the titanium-rich material preparation process is low, and the quality of obtained products is high; a large amount of pollution is generated in the traditional process for preparing the titanium-rich material through ilmenite and a leaching agent used in the method has the beneficial effects of being environment-friendly and free of toxin, so that the leaching process is more environment-friendly; the leaching agent recycling process in the traditional leaching process is complex, and in the method, the redundant leaching agent can be recycled only through cooling crystallization, and the recycling process is simpler and more efficient; and in the traditional process for preparing the titanium-rich material through the ilmenite, a reagent reacts with titanium components, so that the recycling rate of the titanium components is low, however, under the condition mentioned in the method, the leaching agent does not react with the titanium components in the ilmenite, and the recycling rate of the titanium components generated in the method is higher.
