Abstract: 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.

Abstract: 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.

Abstract: A diatomaceous earth product with low crystalline silica content after at least one calcination step of between about 927° C. (1700° F.) and about 1149° C. (2100° F.) is disclosed. The product comprises natural diatomaceous earth and at least one binding agent comprising potassium silicate. Further the product comprises no more than about 4.0 wt % of crystalline silica and has a permeability in the range of about 0.3 darcy to greater than about 20 darcy. A process for making such diatomaceous earth product with a low crystalline silica content is disclosed. Moreover, a diatomaceous earth filter aid comprising such a diatomaceous earth product is disclosed.

Abstract: Processes for manufacturing low soluble iron diatomite filter aids and such filter aids are disclosed. Aluminum oxide and/or aluminum hydroxide are used as additives when preparing the flux-calcined diatomite filter aids. 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 iron levels. For instance, disclosed filter aids of about 0.5 to about 2.0 Darcy were made using either an aluminum oxide or aluminum hydroxide additive with soda ash. The disclosed filter aids may have an EBC soluble iron content of less than 80 ppm versus 130 ppm for similar filter aids that were made from the same ore and flux-calcined with just soda ash.

Abstract: Described herein is a monolithic cementitious article with one or more pre-formed shaped regions. The shaped regions are generally channels that extend through a portion of the article or span the full article. The article includes one or more openings at least one of its ends. The article has a low apparent density with a high strength as well as high performance characteristics. The article when manufactured is suitable for use as a building product, such as siding, panel, trim, fascia, roofing, crown molding, decking, and fencing.

Abstract: A process for manufacturing low soluble iron, medium flow rate diatomite filter aids and such filter aids are disclosed. Sodium aluminate is used as an additive. 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 much lower iron solubilities. For instance, disclosed filter aids of about 0.3 to about 2.0 Darcy were made using an alkali aluminate as an additive/flux agent to have an EBC soluble iron content of less than 100 ppm versus more than 140 ppm for similar filter aids that were made from the same ore and flux-calcined with soda ash.
