MERN - Exploration des silicates d?alumine

Les teneurs en sillimanite varient de 2,5 à 9 % (Cavanagh, 2001). La sillimanite n'est pas très abondante dans ces indices mais comme elle se présente en gros cristaux, elle pourrait être plus facile à concentrer. Toutefois, il n'y a eu aucun essai de concentration de la sillimanite sur ces échantillons de roche (Jacob, non publié).

Kyanite and Related Minerals Statistics and Information

Kyanite, andalusite, and sillimanite are anhydrous aluminosilicate minerals that have the same chemical formula, Al 2 SiO 5, but differ in crystal structure and physical properties. When calcined at high temperatures (around 1,350° C to 1,380° C for kyanite and slightly higher for andalusite and sillimanite), these minerals are converted to mullite, 3Al 2 O 3 ·2SiO 2, and silica, SiO 2 ...
