Abstract
Almost all copper slags contain a considerable amount of Cu (0.5 - 3.7%) close to or even higher than copper ores. A number of methods for metal recovery from copper slag were reported These methods can be classified into three categories, flotation, leaching and roasting. Sulfide flotation method for the recovery of copper from Kazahstan copper furnace slag is discussed in this investigation. 50% of copper from the slag was recovered by sulfide flotation at pH 4. meanwhile 67% of copper from the slag was recovered at pH 11. Higher copper recovery result at pH 11 rather than that at pH 4 was caused by the fact that copper sulfides were floated in particle size fraction over $100{\mu}m$ in concentrates at pH 11. When the slag were ground below $74{\mu}m$by ball milling, the recovery of copper by floation in slag improved to 78 - 83% because of copper liberation effect.
