· It further indicates that the titanium will be recovered by increasing the electrolysis time even at the low cell voltage of 2.0 V. The oxygen content in the intermediate layer was also checked by EDS mapping (shown in Fig. 8c ). The low oxygen content (0.02 mol %) proves that the titanium dioxide is reduced directly to titanium.
The optimum conditions for hydrolyzing experiments are an H + concentration of 0.75 g·L −1, hydrolyzing temperature of 100 °C, and hydrolyzing time of 180 min, and the hydrolyzing rate of titanium in acid leaching liquor is 96.80%. After the leaching and hydrolyzing experiments, the recovery rate of titanium from the Ti-bearing slag is 89.45%.
