Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon oxide tetrahedrons sandwiched with a layer of aluminum oxide octahedron. Due to the layered structure formed by the montmor...
