Mill tailings were disposed of in an area below the mill. The concentrated ore and the direct shipping high-grade ore were loaded into bags for shipment by rail. In 1916 an innovative ammonia leaching plant was constructed to further recover the copper oxides from the tailings. In 1925, flotation was introduced to boost total recovery to 96%.

Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.

mill to the west. This mill crushes and grinds ore from mines in the Greater Sudbury area and separates the powdered rock into nickel and copper concentrates that are then sent to the nearby Copper Cliff smelter for further processing. On the far western skyline beyond the mill is the northern headframe of the Copper Cliff Mine.
