Abstract
An animal litter such as a clay material is treated to reduce the bulk density thereof by contacting the clay material with an aqueous electrolyte solution and then heating at an elevated temperature. Substantial reductions in bulk density have been achieved without reducing the absorption capacity of the clay granule.
Claims20
A bentonite clay which has a bulk density of less than 750 g/L.
A method of reducing the bulk density of clay granules comprising treating the clay granules with an aqueous solution of an electrolyte and then heating to an elevated temperature sufficient to reduce the bulk density of the clay granules.
