Abstract
This invention relates to highly purified biogenic silica product obtained from diatomite and methods for preparing same. More particularly, this invention pertains to highly purified non-calcined, calcined, and flux-calcined diatomite products which bear the distinguishing porous and intricate structure of silica unique to diatomite and which have an extraordinarily high silica (i.e., silicon dioxide, SiO.sub.2) content and low density, resulting in high silica specific volume. These products often also exhibit exceptionally low soluble metals content and/or extreme brightness.
