Diatom

Typical diatomite processing involves a series of crushing, drying, size-reduction, and calcining steps, using heated air for conveying and classifying within the plant. The analysis of oven-dried crude ore blocks typically shows 80–90% silica (SiO 2 ) plus alumina (2–4% attributed mostly to clay minerals) and hematite (0.5–2%).
