Diatomite and Diatomaceous Earth

What is Diatomite? Diatomite is a friable light-colored sedimentary rock that is mainly composed of the siliceous skeletal remains of diatoms. It is a very porous rock with a fine particle size and a low specific gravity. These properties make it useful as a filter media, an absorbent, and as a lightweight filler for rubber, paint, and plastics.

The diatomite excavation also has increased the phosphorus load by 20% and the nitrogen load by more than 90%. Thus, phosphate precipitation from mining effluents was encouraged, and may eventually save this lake area from unwanted Anabaena blooms. A Conservation Act for the Myvatn area was signed by the Icelandic President in 1974.
