- n. A clay mineral that is a constituent of fuller's earth and bentonite
Sorry, no etymologies found.
Fuller’s earth is composed of the mineral palygorskite (at one time this mineral was called "attapulgite").
Naturally occurring attapulgite clays and zeolites are also used in nanofilters.
A study using attapulgite clay membranes to filter wastewater from a milk factory in Algeria has shown they can economically and effectively reduce whey and other organic matter in wastewater, making it safe to drink.
Fuller’s earth: Major producers of fuller’s earth are the United States (attapulgite, smectite), Spain (attapulgite, sepiolite), and Senegal (attapulgite).
