Recovery Of Copper From Copper Slag And

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 maximum copper and iron extractions achieved with the slag were 260 and 625 respectively as opposed to the slag flotation tailings where the maximum copper
