Sillimanite Separation Process
Abstract: 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. Further, the non-magnetic minerals are subjected to a matrix of wet operations and a concentrate of sillimanite and quartz is achieved as an output of the matrix of wet operations. The process further comprises drying and processing a concentrate of sillimanite and quartz and separating sillimanite from said concentrate through utilization of difference in surface conductivity of sillimanite with respect to other minerals.
