Laboratory batch flotation tests were conducted on copper converter slags to evaluate the relative merits of recovering copper from slow- cooled versus water-quenched slags. Three slags containing 1.6, 5.0, and 6.6 percent copper were used. More than 90 percent of the copper was recovered in a rougher concentrate leaving a 0.2- to 0.3- percent copper tailings when treating slow-cooled slag.
