Recovery Of Iron In Copper Tails

The obtained results reveal that the recovery of copper and cobalt depends on the reagents dosage . Indeed, the increase in the reagents dosage of 17 results in significant drops in the recovery of copper 18 and cobalt 31 during the roughing flotation of tailings. Consequently, a concentrate grading 5.50 in copper and 4.15 in cobalt is .
