Bentonite bound for success - Industrial Minerals

bit. Wyoming bentonite is the global standard grade for drilling applications. IIron ore pelletisation (IOP) uses bentonite as a binding ron ore pelletisation (IOP) agent, and is added to dry iron ore to form pellets. Sodium bentonite is preferred for its excellent plasticity, dry bonding strength and high mechanical strength at high temperatures.
