Use of cable bolts to reinforce the hanging pillars and improve the ore
Abstract: There is variability in the geometry of the ore outline, particularly between the footwall (FW) and hanging wall (HW), across the strike length of the various orebodies at Copper Cliff Mine. This geometry creates a requirement to plan transverse sills on one side of the orebody and longitudinal sills on the other side of the orebody on certain levels.

Iron ore mining and dressing
Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.
