The effect of anatase, rutile and sodium titanate on the dissolution of boehmite and gibbsite at 90C
Industrial plants that refine bauxite to alumina using the high temperature process have always held thebelief that anatase was detrimental to the extraction of boehmite while rutile was not. This study shows that this effect is real and that it is observable at temperatures as low as 90 C. The extr...

| description | Industrial plants that refine bauxite to alumina using the high temperature process have always held thebelief that anatase was detrimental to the extraction of boehmite while rutile was not. This study shows that this effect is real and that it is observable at temperatures as low as 90 C. The extraction of gibbsite is shown to be unaffected which leads us to believe that the kinetics of both the Ti-bearing mineral and the Al-bearing mineral is important in this phenomenon. In addition, it is shown that not only is the presence of anatase an issue in boehmite extraction but so too is the presence of sodium titanate. Rutile was found to have the least impact of the three mineral phases. |
