Dry-based processes such as crushing, milling, sieving, magnetic and gravity separation were employed in order to investigate the purification characteristics of bentonite. The CECs of Gampo 13 and 35 bentonites were estimated at 88.3 and 93.9 meq/100 g and the samples contained quartz and feldspar as impurity minerals. According to the physical properties of constituent minerals of bentonite, the purification techniques were adopted to enhance the grade of montmorillonite. High grade of montmorillonite could be obtained by the combination of each process. Consequently, the recovery of final products of Gampo 13 and 35 bentonite were 68.6 and 49.5%, and the CECs of them were 96.9 and 109.6 meq/100 g, respectively.

Wet purification process for the selective separation of montmorillonite from Gampo 13 and 35 bentonite ores was studied using physical processes such as ultrasonic scrubbing, decantation and centrifugation. Ultrasonic Scrubbing of Gampo 13 and 35 bentonite ores was revealed excellent result at 7 wt.% of slurry density and was almost finished within 30 minutes in the sample of Gampo 13 and 10 minutes in the sample of Gampo 35, respectively. After decantation, approximately 52 wt,% from the bentonite of Gampo 13 and 64wt.% from the bentonite of Gampo 35 were recovered as purified products and the CEC was reached up to 119.4 meq/100 g and 124.5 meq/100 g, respectively. Particle separation by centrifugation showed that most of the impurity minerals such as quartz and feldspar were removed within the condition of 1.000 rpm.
