Enrichment of Colemanite Tailing by using Attrition Scrubbing and Decrepitation Methods

25422

This study investigates the upgrading possibilities of the tailings of Eti Maden Bigadiç Boron concentration plant. Firstly, it was planned to compose a pre-concentrated product by way of clay removal from tailing in the experimental studies. The tailing samples have been tested by attrition scrubbing method in a constant stirring rate and in the several pulp densities. From these tests, a pre-concentrate containing 23.78% B_2O_3 grade was produced. The decrepitation experiments were applied on the pre-concentrate to profit from the disintegration of colemanite minerals by heating in order to obtain a higher grade concentrate. As a result of the decrepitation tests, a concentrate containing 45.57% B_2O_3 grade was obtained with a recovery of 88.47% B_2O_3.
