| Abstract | ABSTRACT: The industrial applications of Fullers ' Earth are discussed in-cluding those of the clay in its natural form, calcium montmorillonite, and after modification by acid activation or sodium exchange. Special consideration is given to uses in oil refining, foundry bonding, civil engineering, and agriculture. The deposits of mortmoriUonite clay found in Britain have calcium as the exchange-able ion. These deposits have been excavated and used commercially for a con-siderable number of years. The Romans used the clay for 'fulling ' which was a method for degreasing wool or woollen cloth by treating it with a clay-water slurry. Although the natural calcium montmorillonite has many applications, ways of improving and increasing its uses have been developed. First it was found that acid treatment increased the ability of the mineral to remove colour bodies from oils and other liquids. This led to the development of a new type of fullers ' earth, the acid activated clay. More recently the discovery of a commercially economic process for converting the clay, by ion exchange, into the sodium form, brought all the applications of this swelling clay within the scope of what was originally calcium |
