Water is removed from the iron ore concentrate on vacuum disc filters in the pellet plant of Cliffs Natural Resources in Hibbing, Minn. After the water is removed, the concentrate is combined with a clay binder and then transported on conveyor belts to the balling drum where is shaped into little balls. Then they are sent to the furnace to harden. (Amanda Hansmeyer / News Tribune)
