How to Recover Copper from Slag by Flotation

Based on the treatment of 1,000 tons of slag per day, production cost of treating quenched converter slag would be $1.85 versus $2.37 per ton of slow-cooled slag. The cost advantage of processing quenched slags results from elimination of the slow-cooling and crushing operations inherent in the treatment of slow-cooled slags.
