Bleaching earth, often called fuller’s earth, is a type of clay mined in Asia, England, India, and the United States. Once obtained from the earth, this mineral-rich substance is processed and used for its absorbing, bleaching, and filtering properties. After industrial use, the earth must again undergo processing in which it is recycled for reuse or rendered safe for disposal.

Attapulgite, bentonite, and montmorillonite clays are the substances most commonly found in bleaching earth, individually or in combination. In its raw state, the clay mostly contains silica, followed by aluminum. This clay also commonly contains iron, magnesium and calcium. The clay deposits resemble soil and can range in color from buff or tan to yellow or pure white. It is highly absorbent and typically has a smooth, greasy feel.

Bleaching clay has the ability to absorb unpleasant odors, including those produced by ammonia, sulfurs, and tars.Bleaching Earth can be used for paint, daub, ink, resin, grease, adhesives, putty, cosmetics, liquid fertilizer, granule fertilizer, molecular sieve, decoration board, plastics, rubber, mud for well drilling, etc.
