Beneficiation and applications of an Egyptian bentonite
Beneficiation of the bentonite oreThe results of beneficiation showed that applying a flowsheet based on attrition scrubbing of the crushed bentonite ore followed by classification with a hydrocyclone succeeded in removing much of the associated quartz and calcite as an underflow (about 15 wt.%) fraction. So, this underflow fraction was discarded.
