Overview — clay mineral applications

Structure of p~ilygorskite (attapulgite). fuller's earth. Therefore the term fuller's earth is quite often used for palygor- skite (attapulgite), sepiolite and smectite clays that have sorptive qualities. Palygorskite and sepiolite are normally light tan or cream to brown in color although some have a blue-green tint.
