Bentonite And Fuller's Earth Resources Of The United
Jun 08, 2012 Most clay deposits are high in either sodium (sodium bentonite clay) or calcium (calcium bentonite clay). Generally speaking, clays that are high in sodium and low in calcium are used for industrial applications—pond seal, drilling support, etc.—because these clays swell than others.Aug 25, 2020 Components How It Works. The main component is montmorillonite, a soft clay formed by layers of silica and alumina. Montmorillonite is normally bound to many clay minerals, especially sodium, calcium, magnesium, and aluminum [8, 3]. Bentonite may also contain small amounts of impurities such as other clays (illite, kaolinite) and crystalline silica (quartz, cristobalite).
