The particle size of as-received sillimanite mineral was in the range of 200–300 μm which was reduced to 1–20 μm and 75–106 μm using a ball milling set-up (PM100, Retsch, Germany). Ball milling of sillimanite was done at 283 rpm for 24 h with a ball size of 12 mm. The ball to powder mass ratio was kept as 10:1.The study of grinding kinetics using ball mill indicate that the slope value obtained for thermally treated sillimanite is lower than the natural sillimanite, which shows that the sample responded ...


Sillimanite is the best raw material for the manufacture of high alumina refractories or 55-60% alumina bricks.

Chips range from mini to small with an average size of small.


Sillimanite, named after the American chemist Benjamin Silliman, is an aluminosilicate mineral with the chemical formula Al2SiO5 The term Sillimanite was first described in 1824 for an occurrence in Chester, US. A common form of Sillimanite is known as fibrolite. It is named fibrolite because the minerals occur like a bunch of fiber twisted ...Described herein is a method to separate sillimanite from beach sand. The method includes passing the beach sand through a preliminary filter screen to achieve uniform grain size of beach sand. After this step the beach sand of uniform grain size is subjected to a magnetic separation process to separate out non-magnetic minerals of the beach sand.

The unitized Sillimanite gas field stretches across the UK and the Dutch Continental Shelves in licence block 44/19a on the UK side and blocks D12a and D12b on the Dutch side. A treaty between the UK and Dutch governments entered into force in July 2018. The Sillimanite South field is located entirely in block D12a.Sillimanite is composed of aluminum silicate, which is a polymorph; sillimanite, kyanite and andalusite all share the same chemical composition (Al2SiO5), but each exhibit differing unique crystal structures. Sillimanite forms as orthorhombic, hexagonal crystals, whereas kyanite and andalusite crystals are both formed as triclinic crystals.
