Information @ a Glance

Contents on the CD Rom

• Diatomite (diatomaceous earth, kiselguhr) is a sedimentary rock of marine or lacustrine deposition.
• Diatomite can be considered as inert due to the chemical composition, which imply that diatomite does not affect taste, smell or colour.
• Diatomite is often referred to as a diatomaceous earth, but this appellation may be inappropriate, especially for clays, even though they also are the result of trillions of defunct diatoms piling up.
• Diatomaceous earth, also known as DE, TSS, diatomite, diahydro, kieselguhr, kieselgur and celite.
• Diatomite is a powdery, non-metallic mineral composed of the fossilised skeletal remains of microscopic single-celled aquatic plants called diatoms.
• Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.
• Most diatomite deposits in the Philippines is almost always refined/ processed due to clay impurities, which reduces the good physical properties required by industrial users.
• Diatomite can also be upgraded by leaching, a process by which a soluble metallic compound is removed from a mineral by selectively dissolving it in a suitable solvent like sulfuric acid.
• Diatomite mining in the United States is all open pit, normally using some combination of bulldozers, scraper-carriers, power shovels, and trucks to remove overburden and the crude material.
• The processing of uncalcined or natural-grade diatomite consists of crushing and drying.
• The preparation of hierarchical structured zeolites through transforming the diatomaceous silica into zeolite by a vapor-phase transport (VPT) method.
• Diatomite is used as a filtration aid, as a mild abrasive, as a mechanical insecticide, as an absorbent for liquids, as cat litter, as an activator in blood clotting studies, and as a component of dynamite.
• Diatomite has been widely used in sound and heat insulation as filters, abrasives and in the manufacture of explosives.
• Diatomite as filter aid is used primarily to increase flow rate and remove visible suspended matters.
• Filtration is one of the most widely used operations in industrial processing, and diatomite has been an indispensable filter aid material for more than 60 years.
• Diatomaceous earths and porous silica-derived compounds (e.g., calcium silicate and silicon dioxide) have been widely used as food-grade anticaking, clarifying, and filtration agents , for cell and enzyme immobilization , and for controlled-release formulations of biologically active molecules.
• A microprobe Raman technique was used to characterize a selection of diatomite samples.
• The United States is the largest producer and consumer of diatomite in the world.
• On the basis of historical production figures, estimated U.S. diatomite-production capacity is currently about 800,000 metric tons per year (t/yr).
• The USA and China continue to dominate world production, with future expansion in diatomite production likely to be concentrated in China.
• Although the market for diatomite is estimated to remain stable in the short-term, the longer-term outlook may be less optimistic.
• Diatomite pricing is very competitive and leading producers have traditionally discounted list prices to retain market share.
