Summary:Suzhou kaolin, strongly coagulated and containing impurity minerals such as alunite, quartz and heavy minerals, is unsuitable for use as a ceramic raw material and has been mainly used for paper filler. In order to use Suzhou kaolin as a ceramic raw material it is necessary to improve the dispersion behaviour and the purity. In the present study, the separability of two kinds of deflocculants for Suzhou kaolin have been examined; one is water- glass and the other is the mixture of water-glass and organic deflocculant. Suzhou kaolin and the elutriated samples were characterized by XRD, thermal analysis, TEM, specific surface area, chemical analysis and titration. It was found that impurity minerals such as alunite and quartz in Suzhou kaolin were successfully eliminated by the elutriation with water-glass and an organic deflocculant.
