摘要： Low soluble arsenic diatomite filter aids and method of making such filter aids are disclosed. Alumina and/or aluminum hydroxide (ATH) are used as additives when preparing the filter aids, which may be straight-calcined or flux-calcined. Alternatively, activated alumina may be added to an already straight-calcined or flux-calcined diatomite filter aid. As compared to either straight-calcined or soda ash flux-calcined diatomite filter aids of similar permeabilities made from the same ore, the disclosed filter aids have lower soluble arsenic content. The disclosed filter aids have a soluble arsenic content, either by the OIV, EBC or USFCC method, of about 60% or less than the straight or flux -calcined diatomite filter aids of similar permeability without an alumina or ATH additive.

摘要： Diatomaceous earth products with reduced amounts of cristobalite and higher Y values are disclosed. The diatomaceous earth products are prepared in a conventional manner to produce a flux-calcine diatomaceous earth. The flux-calcine diatomaceous earth is mixed with potassium hydroxide and the mixture is then heated. The combination of the potassium hydroxide and post-calcining heat treatment results in a diatomaceous earth product with reduced amounts of cristobalite and a whiter, brighter appearance.
