The milled slag was dewa- tered and placed into the flotation cell. Water was added to dilute the slurry up to approximately 30% solids by mass. Reagents specific to each test were added and a conditioning time of 3 min was allowed. Air was bubbled through the agitated slurry at a rate of 2–3 l/min and agitation was set at 1380 rpm.
>RECOVERY OF COPPER FROM COPPER SLAG AND COPPER …
slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation. Based on the chemical compositions of the slag and the slag flotation tailings (Table 1), it can be concluded that the copper dissolved from the slag flotation tailings mainly originates ...

In terms of copper recovery, it is thus quite important how the copper slag has been processed and cooled post the smelting or converting furnace, EF and prior to the milling and flotation step. Far less important, in this respect, is the actual smelting and converting technology upstream of the slag cleaning step.

The main drawback in the current process is that the final flotation tailings grades are in excess of 0.9% Cu. This copper content is considered too high to be lost in the final waste stream. The milling response of the different slags showed that the reverberatory slag mills much more easily in comparison to the TSL slag and the converter slag.
