These clays are mined in specific regions of the country but have not been fully characterized in terms of their properties for potential application in a number of industries. Bentonite was found to …

 — Since ferric tetroxide (Fe3O4) has strong magnetic properties, coating amorphous silica (SiO2) with Fe3O4 nanoparticles can protect the magnetic Fe3O4 particles and form a new magnetic adsorbent with a core–shell structure and small pore size, the strong magnetic properties of which can efficiently solve the problem of the …

 — 1. What is Bentonite? Bentonite, also referred to as "porphyry" or "bentonite," is a non-metallic mineral primarily composed of montmorillonite.It typically contains small amounts of illite, kaolinite, zeolite, feldspar, and calcite. The composition of montmorillonite determines the natural bentonite's properties and value.
