What is diatomite used for?
Diatomite is now used principally as a filter aid; but it has many other applications, such as an absorbent for industrial spills and as pet litter, a filler in a variety of products from paints to dry chemicals, an insulation material as sawn and molded shapes as well as loose granular, a mild abrasive in polishes.
What is diatomite made of?
Diatomaceous earth is made from the fossilized remains of tiny, aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. Over a long period of time, diatoms accumulated in the sediment of rivers, streams, lakes, and oceans. Today, silica deposits are mined from these areas.
What type of sedimentary rock is diatomite?
Diatomite is a siliceous sedimentary rock composed mainly of the fossilised skeletal remains of diatoms, which are single-celled organisms related to algae.
What element essential to life does diatomite provide?
Diatomite, also known as diatomaceous earth, is the naturally occurring fossilized remains of diatoms. Diatoms are single-celled aquatic algae. They belong to the class of golden brown algae known as Bacillariophyceae….Edit This Favorite.

What does diatomite look like?
Diatomite is a soft, friable and very fine-grained siliceous sedimentary rock composed of the remains of fossilized diatoms. Chalky to the touch and often light in color, diatomite can be white if pure, but more commonly it is buff to gray in situ, or sometimes black.
What is diatomite filter media?
Diatomaceous Earth Filter Media is designed to filter the smallest particles out of your water and leave your pool sparkling clear. Made from microscopic, fossilized algae, Diatomaceous Earth (DE) is a powder that acts as millions of tiny sponges, absorbing and trapping particles that contaminate and cloud your water.
Where can I find diatomite?
The largest known diatomite deposit in the world is located in Lompoc, Calif. In the United States, diatomite is produced by seven companies at 10 separate mining areas in California, Nevada, Oregon and Washington.
How is diatomite rock formed?
Diatomite is a soft, friable and very fine-grained siliceous sedimentary rock composed of the remains of fossilized diatoms. Diatomite deposits formed when the skeletons of dead diatoms accumulated in either marine or freshwater environments and were subsequently compressed and lithified.
Where do you find diatomite?
In the United States, large deposits of diatomite are found in California, Nevada, Washington and Oregon. Of these states, California and Nevada produce the largest amount of diatomite. Significant producers of diatomite worldwide include France, China, Denmark, Russia, and Algeria.
What minerals does diatomite have?
The typical chemical composition of oven-dried diatomaceous earth is 80–90% silica, with 2–4% alumina (attributed mostly to clay minerals), and 0.5–2% iron oxide. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled protist.
What is perlite filter media?
Perlite is an important filtration media used in the clarification of beverages including beer, wine and fruit juices and in swimming pool and other water filtration applications. Perlite is a generic name for a naturally occurring siliceous volcanic rock.
