Typical flotation recoveries are about 85% for copper and 75% for cobalt from sulphide ores, and recovery of 75% of copper and only 45% of cobalt from oxide ores (Fisher and Treadgold, 2009). For mixed oxide-sulphide ore, recoveries are lower: up to 80% of the copper and 60% of the cobalt in the sulphides and only 60% of the copper and 40% of ...
