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.
