Diatomite Statistics and Information - USGS

Diatomite is a chalk-like, soft, friable, earthy, very fine-grained, siliceous sedimentary rock, usually light in color (white if pure, commonly buff to gray in situ, and rarely black). It is very finely porous, very low in density (floating on water at least until saturated), and essentially chemically inert in

Diatomite Mining and Processing

Diatomite does not need to be blasted as it is a soft, friable ore. The stockpiled material is then hauled to the processing plant for crushing, drying, milling and often calcining. Going into the crusher, the pieces may be as large as a small car, but coming out they will be the size of a pea.

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%).
