Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earths surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.
Jun 26, 2012 This two-part series from Eddie Starnater of Practical Primitive shows you how to extract the clay from raw soil and process it into a material that can be used for pottery. In the first part, Eddie teaches a simple water extraction process that uses a series of mixing and decanting steps to remove sand and silt, followed by pouch filtration to remove excess water.
Mining amp Processing. Bentonite is surface mined through a process called back-casting where reclamation is performed by filling the mining pits with soils from subsequent pits while the mine is in production. Typically the topsoil layer is about

The process by which some clay minerals swell when they take up water is reversible. Swelling clay expands or contracts in response to changes in environmental factors wet and dry conditions, temperature. Hydration and dehydration can vary the thickness of a single clay particle by almost 100 percent ...
