  • Bentonite an overview ScienceDirect Topics

    Bentonites are nonconsolidated sedimentary rocks and belong to the silica clay minerals which are important for industry. The main constituent is montmorillonite. As the most common minor constituents in European deposits, calcite, quartz, cristobalite (C-Opal), feldspar, gypsum, pyrite, mica, chlorite, and illite are to be mentioned. The term bentonite does not describe any mineral phase, as
