文摘

A novel method for direct extraction of perovskite from Ti-slag is established. There is 88.3% perovskite with 1.4% SiO2 in residue using the present method. Extraction of perovskite was controlled by interface transfer and solid diffusion. The strategy can be extended for resources of complex high silicate minerals.
