concentration titanium process

Process for concentration of titanium containing

1. A process for the concentration of titanium containing anatase ore comprising: (a) calcining the said anatase ore in a non-reducing atmosphere at a temperature below that of rutilization; (b) cooling said calcined ore; (c) reducing the cooled ore in a reducing atmosphere at temperatures between 400° C.

The effect of T-atom ratio and TPAOH concentration

2020-10-1  For instance, high TPAOH concentration is necessary to induce titanium re-insertion into framework position and to create inter-connected open meso/macropore in TS-1 with low Si/Ti ratio. On the contrary, TPAOH treatment even at high concentration was found to be ineffective in the post-synthesis treatment of low titanium containing TS-1 samples and result in a phase change from

Leaching Process by Sulfuric Acid Reactions

2020-5-27  The degree of titanium extraction into solution was found to increase with increasing sulfuric acid concentration [18]. However, when using H2SO4 solutions with a concentration above 14 M, reduced e ciency of the leaching process was observed. According to the literature, maximum e ciency was found to be within a sulfuric acid concentration of 9–17 M.
