Bleaching Earth

Process for making acid activated bleaching earth using high susceptibility source clay and novel bleaching earth product

A process for making acid-activated bleaching earth from a crude attapulgite clay. A crude is selected which is mildly acidic and contains at least about 90% attapulgite. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower production costs (no washing, filtering, or waste treatment steps) and environmental soundness (no harmful environmental waste products are produced).
