Chengdu Library and Information Center, Chinese Academy of Sciences，Chengdu 610041, China; 2. University of Chinese Academy of Sciences, Beijing 100049, China ） Abstract: Patents of vanadium titanium magnetite comprehensive utilization were analyzed in this paper. Focusing on the pyrometallurgical process and hydrometallurgical process for enriching and separating vanadium titanium magnetite, comprehensive utilization technology of multi-metal ore while using more than one element at the same time, and production technology of vanadium-titanium products, the basic trends of the global patents were analyzed, including the overall trends, geographical distribution, important competitors, technology trends and so on, and the technical composition of active patents in China were mainly analyzed. The results showed that the technology of vanadium titanium magnetite comprehensive utilization is in rapid development period, the patents involving vanadium-t
