Diatomite is the fossilized skeletal remains of microscopic single-celled aquatic plants known as diatoms (algae). A crystal shell protects these tiny organisms. When the organisms die, the shells pile up on the bottom of oceans and lakes to form deposits. These deposits are then mined from underwater beds or from ancient dried lake bottoms. Once they have been mined they can be milled or processed for a variety of uses.
