Abstract

This study was conducted to determin basic mineral compositions, chemical components, description of particle size distribution and whiteness for 32 items of insoluble mineral substances, i.e., 3 items of diatomaceus earth, 1 item of kaolin, 10 items of bentonite, 13 items of acid clay, 3 items of talc and 2 items of perlite. The chemical components and XRD (X-Ray diffractometer) for insoluble mineral substances, were similar with those of the reported references except kaolin. However, whiteness was determined in 90% level for talc, diatomaceus earth and kaolin. The contents of heavy metals in insoluble mineral substances were determined as follows : Pb, $nd{\sim}23.10$ ppm ; Cd, $nd{\sim}0.67$ ppm ; Hg, $nd{\sim}0.58$ ppm ; As, $nd{\sim}1.42$ ppm ; Cu, $nd{\sim}39.35$ ppm. These data were significanty lower than the references.
