Jun 05, 2012· Introduction. Diatomite, a soft, porous, fine-grained, lightweight, siliceous sedimentary rock, is produced by the accumulation and compaction of diatom (Class Bacillariophyceae) remains. The cell wall of living diatoms is impregnated with silica (amorphous hydrous, or opaline (SiO 2. n H 2 O)), which preserves ornate and highly …

Diatomaceous earth. Diatomaceous earth or diatomite is a light-colored sedimentary rock composed chiefly of siliceous shells (frustules) of diatoms. Diatomaceous earth is a soft and friable rock. It leaves hands dusty if touched and has a fragile feel as if it has a delicate and light-weight internal structure. This feeling is not misleading.

The mining and processing of diatomite is delicate and complicated. It requires large processing facilities and heavy earth moving equipment. To minimize costs, diatomite is usually mined in open-pit, surface mines (although some operations do use underground extraction methods). In surface mining, a considerable thickness of earth, known as ...
