  • Ore

    Ore mineralogy affects the shape and size distribution of iron ore particles. In the same crushing circuit, friable ore textures tend to generate more fine materials. Ore particles of different mineralogical characteristics also tend to have different physical characteristics and are subject to different breakage mechanisms when crushed.

    The ore is then reclaimed through reclaim feeders into a Semi-Autogenous Grinding (SAG) mill before being transferred into a Ball mill. From the Ball Mill the undersize material reports to vibration screens which separate the material into the correct size distribution for the leaching stage. Oversize material is fed back to the ball mill.
