What is taconite and where does it come from

May 30 2022Taconite pellets are made from taconite ore cherty or jaspery rock with a high iron content To make these pellets the hard taconite ore is blasted and then ground down with water to a fine powder The fine iron rich particles mostly of magnetite are extracted from the powder by use of magnetism Minnesota Iron Mining Process

Taconite Production

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 flux As a last step it is rolled into pellets about one centimeter in diameter that contain approximately 65% iron

Introduction to Iron ore Pellets and Pelletizing processes

Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh mm with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a
