Sepiolite is a naturally occurring clay mineral of sedimentary origin. It is a non-swelling, lightweight, porous clay with a large specific surface area. Chemically, sepiolite is a hydrous magnesium silicate whose individual particles have a needle-like morphology. The high surface area and porosity of this clay account for its outstanding absorption capacity for liquids. Sepiolite granules do not disintegrate even when saturated with liquids. Main Applications : Animal feed additive ( E-562 ) Cat & pet litters Waste treatment Moisture control Carrier for chemicals Industrial spillages absorbents Construction Bitumens Polymer fillers Rheological additives

BENTONITE Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. Other smectite group minerals include hectorite, saponite, beidelite and nontronite. Smectites are clay minerals, i.e. they consist of individual crystallites the majority of which are <2µm in the largest dimension. Main Applications : Agriculture and Animal Feeds Asphalt Emulsifiers Ceramics Construction and Civil Engineering Detergents Environmental Sealants Horizontal Drilling Household Cleaners Industrial Coatings Iron Ore Pelletizing Metal Casting Oils/Food Processing Oil and Gas Drilling Paints, Dyes and Polishes Papermaking and Paper Recycling Pet Products Pharmaceuticals, Cosmetics, and Medicine Wastewater Treatment Wine and Juice Clarification

SILICA The name Silica covers a range of minerals composed of silicon and oxygen, the two most abundant elements in the earth’s crust. Silica exists in ten different crystalline forms. By far the most common of these is quartz. It is hard, chemically inert and has a high melting point. Silica is sold as sand and processed for multiple uses. Glass is made from pure quartz silica because of its transparency or translucency. The Egyptians discovered these properties thousands of years ago, but there are many other applications for silica, from building materials to the precious silicon chip, produced from high purity quartz and extremely fine cristobalite sand. Professional footballers and golfers also benefit from better playing surfaces thanks to silica sand root-zone products. Main Applications : Paints & plastics Ceramics Glass Filtration Sports & leisure Construction Sealants & adhesives Chemicals Foundry Oilfield Metallurgical applications Agriculture

Zeolites have many useful purposes. They can perform ion exchange, filtering, odor removal, chemical sieve, and gas absorption tasks. The most well-known use for zeolites is in water softeners. Calcium in water can cause it to be "hard" and capable of forming scale and other problems. Zeolites charged with the much less damaging sodium ions can allow the hard water to pass through its structure and exchange the calcium for the sodium ions. This process is reversible. In a similar way zeolites can absorb ions and molecules and thus act as a filter for odor control, toxin removal and as a chemical sieve. Main Applications : Pollution Control Mining Crops / Pastures Horticulture Stockfeeds Aquaculture Turf Vermiculture
