Bleaching earth is a swelling clay with chemical formula AI2Si40IO(OH)2. It is called swelling clay because it swells greatly in water. The absorption capacity is two to seven times its volume. The absorptive properties of these clays are enhanced by treatment with mineral acid to increase the surface area and pore volume prior to washing, drying and milling to get the desired particle size distribution.
We are into manufacturing of highly active bleaching earth and even produce equivalent to Tonsil grades. Our product is widely accepted in Edible and Non-Edible oil refining, lubricants, Vanaspati Industries, refining of vegetable and animal oils and fats, mineral oils, paraffins and waxes.
