Abstract
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. Lower recoveries and higher copper tailings ranging from 0.5 to 0.6 percent copper were obtained from quenched slag. Grindability studies were made on the respective heat-treated slags. Quenched slags proved more difficult to grind than slow-cooled slags. Cost studies showed that quenched slags can be treated at slightly lower cost than slow-cooled slags. However, the cost advantage of processing quenched slags is more than offset by the higher copper recoveries obtained from slow-cooled slags. This 1972 report is a revision of the original ri 7562, published in 1971.
