What Can Diatomite do for me?

  • Diatomite is highly absorptive with a high capacity for uptake of water and oils. Mount Sylvia make a number of products which absorb up 200% water and oil. Used Diatomite containing no free liquid, that has absorbed Total Petroleum Hydrocarbons C10-C36 (kerosines, diesel, lubricating oils) has been classified by the N.S.W EPA as immobilised solid waste suitable for solid waste landfills.
    Kleensorb is used as a pet litter, industrial spillage absorbent, barbecue grill drip tray bed, and oil and beverage clarifier. Other products Nursery Grade and Granular Grade are also used in this context.

  • Diatomite stimulates healthy growth of plant root systems. It conditions the soil by making silica available to plants and by helping the soil to retain moisture. Purasil is our unique product aimed at this market. It retains water in potting mixes and is used as a grass underlay.
  • Diatomite is used in the building industry. Our Granular Grade and Diatomite Fines Grade are used in the manufacturing of lightweight bricks, blocks, tiles, boards and sheets and is an additive to cements, plasters, mortars and stuccos. It is also used for sound deadening in ship building, roofing, and flooring.
  • Diatomite plays a role in stock feeds and lick blocks. Our Diatomite Fines Grades are used in a number of commercial, proprietary animal feed preparations. Our product Molodri, which is a blend of liquid molasses and diatomite is popular as a feed attractant and appetite stimulant for cattle, horses, sheep, goats, pigs and poultry. Because it’s a powder it’s easy to mix with other stock feeds.
  • Diatomite is finding increasing use as an insecticide. Our Diatomite Fines Grades product is used in commercial sprays against a variety of broad acre pests. Our product Absorbacide has been registered with the AVPMA as an Absorbent Dust Insecticide for the control of various stored product insect pests in farm-stored feed and seed grain, and grain for human consumption. This product is active against a number of insect pests for which we are currently seeking APVMA registration.
