| Summary: | An environmental procedure to extract titanium components and metallic iron from Ti-bearing blast furnace slag is accomplished via three steps, which are high-temperature modification, gravity separation and hydrometallurgy method. The behaviors of metallic iron during the high-temperature modification process are studied. The feasibility of separating rutile from the matrix phase are investigated; based on the feasibility analysis results, the gravity separation experiment is carried out in order to improve the TiO2 content in the slag. The leaching behaviors and kinetics of non-titanium components in the concentrate of gravity separation are investigated. The activation energy of the leaching process is 62.868 kJ/mol, and circulatory leaching and preparation of synthetic rutile experiments are implemented. Finally, an environmental technological route is proposed for comprehensive utilization of Ti-bearing blast furnace slag. |
