Bentonite is a rock mostly constituted by clay minerals (very fine particles with sizes smaller than 2 micrometers). From geological features, Bentonite is clay layers rich of montmorillonite- beidellite which has other companions. It should be noted that Bentonite is not a mineral, but a series of minerals together constitute Bentonite rock. Environment of this rock formation is shallow and low energy waters and temperate climate. Montmorillonite or Bentonite with respect to its abundant applications is categorized as follows.
Substitution Bentonites by sodium
For ceramic tile
For civil engineering, dams, tunnels, concrete and plastic concrete
For earth pit and earthing
For Livestock, poultry and aqua feed
In steel industry
In casting industry
