ABSTRACT:
An adsorbent, absorbent product can be produced from sericitic clays by removing alumina values from such clays with a mineral acid, removing oil contaminants from such clay with a solvent or solvent mixture and removing amorphous silica from them with a caustic solution. The particles of the clay are dried after treatment in these manners. They are then ready to use.
