Based on the resource characteristics and occurrence states of vanadium-titanium magnetite in the Panxi region, this paper systematically sorts out and reviews the research progress of titanium resource extraction technologies in three core fields, namely the practical application of ilmenite concentrate raw materials, the comprehensive development and utilization of titanium extraction from high-titanium blast furnace slag, and the preparation of titanium-containing raw materials through the non-blast furnace smelting process of vanadiumtitanium magnetite concentrate. At the same time, it also conducts in-depth and detailed analysis on the advantages and disadvantages of different titanium extraction processes. The research results clearly show that in the field of ilmenite concentrate raw material application, mainstream technologies such as sulfate process for titanium dioxide production and titanium slag preparation have gradually become mature, and their process stability and industrial adaptability have been verified through long-term practice. However, the hydrochloric acid process for titanium dioxide production and the preparation technology of upgraded titanium slag(synthetic rutile) are currently still restricted by key technical bottlenecks and faces many obstacles in large-scale industrial promotion. In terms of titanium extraction technologies from high-titanium blast furnace slag, most processes are still in the stage of laboratory research and development or pilot-scale testing, and have not yet been industrialized. Among them, the "high-temperature carbonization followed by low-temperature selective chlorination for TiCl4 production" technology has been identified as the core breakthrough direction in this field in the future due to its significant industrialization potential. In addition, the technology of preparing titanium raw materials through non-blast furnace smelting of vanadium-titanium magnetite concentrate is highly consistent with the green development trend strongly advocated by the current iron and steel industry. It can not only improve resource utilization efficiency but also reduce the environmental load during the production process, thus showing a broad application prospect.
