Activated calcium bentonite is the most widely used bentonite in winemaking as it has a high swelling index and a pH of between 9 and 10. It also has a high proportion of exchangeable sodium and calcium. It is obtained by activating natural calcium bentonite with sodium carbonate, and then drying and grinding the resulting mixture. Its proportion of exchangeable sodium depends on the level of,

CHEMICAL COMPOSITION OF BENTONITENutrales

Bentonite is usually formed due to the weathering of volcanic ash, most often in the presence of water. For industrial purposes, there are two main classes of bentonite: Sodium and Calcium bentonite. Our offer offers both main types of bentonite: Sodium bentonite expands when moistened and absorbs several times more dry mass into water. Due to its excellent colloidal properties, it is widely,

The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include filler, sealant, and catalyst in petroleum refining. Calcium bentonite is sometimes marketed as fuller's earth, whose uses overlap with those of other forms of bentonite. Bentonite is used in drilling mudto lubricate and cool the cutting tools, to remove cuttings, and to help pr…

Bentonite contains a high proportion of Na-montmorillonite, a clay mineral that swells in water and endows bentonite with a very low hydraulic con-ductivity (Pusch, 2001). As a result, transport of water and solutes in bentonite is mainly diffusive, with diffusion coefficients that are much smaller than in ordinary water (Mad- sen 1998; Ochs et al. 2001; Bourg et al. 2007).
