The concentrator utilizes rod mills and magnetic separation to produce a magnetite concentrate, which is delivered to the pellet plant. Hibbing Hibbing operations consist of a concentrator that utilizes single stage crushing, AG mills and magnetic separation to produce a magnetite concentrate, which is then delivered to an on-site pellet plant.
Magnetite concentrate is mainly used for pelletizing purposes, but the lack of Chinese end-users with pelletizing facilities meant it was used for sintering instead.
The main AG mill with 28MW gearless motors has a diameter of 12.2m and a length of 11m. The ball mill, the second stage grinding unit, is 7.9m in diameter and 13.6m-long. It is equipped with two 7,800kW motors. Each of the processing lines used 52 magnetic separators, each containing seven press filters and four dewatering buildings.
