Top countries by diatomite production (1970-2018)

Описание: This video presents the world ranking of diatomite producing countries from 1970 to 2018.
The unit of measure of the presented data is tonnes (metric).

Diatomite or kieselgur is a naturally occurring, soft, siliceous sedimentary rock that is crumbled into a fine white to off-white powder. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80–90% silica, with 2–4% alumina and 0.5–2% iron oxide. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled protist. It is used as a filtration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemical catalysts, cat litter, activator in blood clotting studies, a stabilizing component of dynamite, a thermal insulator, and a soil for potted plants and trees like bonsai.
