Advantages of iron ore processing and beneficiation

beneficiation of iron ore mineral processing metallurgycrushing is done in the conventional manner in 2 or 3 stage systems to approximately all minus ¾ inch which is considered good feed for subsequent wet rod and ball mill grinding. the primary rod mill discharge at about minus 10 mesh is treated over wet magnetic cobbers where, on average magnetic taconite ore, about 1/3 of the total

the initial stages of grinding and magnetic separation passes to a hydroclassifier to eliminate the large volume of water in the overflow. some finely divided silica slime is also eliminated in this circuit. the hydroclassifier underflow is generally subjected to at least 3 stages of magnetic separation for further upgrading and production of additional final nonmagnetic tailing. magnetic
