Description
This dataset represents the production of bentonite of an average type, obtained by weighting the market shares of sodium-based bentonite and calcium-based bentonite. For technical details, refer to the production-process datasets of each type of bentonite. The data are mainly sourced from publicly available literature.
Activity Description
The boundary of the production activities of this product covers the bentonite production stage, including processes such as drying, sodium activation, and grinding, which involve emissions of pollutant gases, particulate matter, and water used for dust suppression during fuel combustion.
Process Description
Bentonite is a natural clay mineral with montmorillonite as its core component. Its key characteristics are excellent swelling and cation exchange capacity when exposed to water. With its high viscosity, high expansion, and strong adsorption, bentonite is widely used in drilling mud, casting sand molds, metallurgical pellets, environmental adsorption, and civil engineering anti-seepage applications.
