Copper Iron Flotation

RECOVERY OF COPPER FROM COPPER SLAG AND COPPER .

A common feature of the slag and the slag flotation tailings is higher iron dissolution compared to that of copper. Further, as seen in Figure 2 and 3, higher copper dissolution is accompanied with higher iron dissolution. That is, higher copper and iron extractions were observed with the slag rather than slag flotation tailings. Thus, the .
