In the recent past, iron ore resources from Brazil consisted of relatively highgrade iron ore, commonly processed via multistage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the highgrade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron ores.

The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Grinding is a subprocess of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream subprocess. In many cases, an autogenous mill (AG mill) or a semiautogenous mill (SAG mill) is used for the primary grinding, and a ball mill is used as the secondary for further
