Calcium bentonite is more commonly used as a binder in pelletizing iron ore. Is bentonite environmentally friendly? Bentonite is generally considered to be environmentally friendly because it is a natural material and is non-toxic. However, its environmental impact depends on the specific application and how it is used.
5. Conclusions Iron ore pelletization with bentonite binder works by a different binding mechanism than with FBB. Bentonite is a physical binder, while FBB is a pozzolanic binder. Iron ore concentrate pellets produced with up to 50% of the bentonite replaced by fly-ash exceeded minimum industrial specifications for dry compressive strength.
