An environmental procedure to extract titanium components and metallic iron from Ti-bearing blast furnace slag

Abstract

AbstractAn 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 TiO
