Palygorskite has been grouped with sepiolite and loughlinite (sodium sepiolite) into a mineraI subgroup of hormitic clays. The names of generic clay products may refer to a combination of mineraIs. For instance, the name 'fuller's earth', a product originally used to absorb fat from wool (fullng), is used in the United States to mean palygorskite,
for attapulgites and sepiolite, and the oil retention for bentonites is lower than that for attapulgite, sepiolite and acid-activated bentonites. For these reasons, many refiners prefer bentonite-based natural bleaching earths. The benefit of the natural clays is that they do not act as solid acid catalysts. Instead their main action is by ...
