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 ) content and low density, resulting in high silica specific volume. These products often also exhibit exceptionally low soluble metals content and/or extreme brightness.
