Energy and Environmental Profile of the Mining Industry • Agglomerated The development of techniques of mining and concentrating taconite led to the introduction of the ironore pellet. Pellets are comprised of ore that has been agglomerated into balls. The pellet is the major form of introducing iron into the steelmaking blast furnace.
To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a a last step, it is rolled into pellets .
