The selective flocculation process is efficient in separating impurities from kaolin without using collector. The selective adsorption by flocculants is better effective at pH nine, where negative charges present on the kaolin surfaces help in adsorbing the titanoferrous mineral surfaces by polyacrylamide polymers.
