The slag from the furnaces is a waste product that is sent to the slag dump. The converter matte is slow-cooled to produce a coarse crystalline structure Bessemer matte. This is crushed, ground and separated into metallics, nickel sulphides and copper sulphides by magnetic separation and flotation in the Matte Separation Plant.

However, recovery of copper was about 4 percent lower for the high copper slag (sample C) and 23 percent lower for the low copper slag (sample A). Flotation tailings from the quenched slags ranged from 0.53 to 0.66 percent; slow-cooled slags gave tailings containing from only 0.26 to 0.39 percent copper with lowest analyses for 30-minute grinds.
