Potassium amyl xanthate (PAX) and Flotanol CO 7 were used in all tests as the primary collector and frother. Different secondary collectors and sulphidizing agents were used to
RECOVERY OF COPPER FROM COPPER SLAG -
That is, higher copper and iron extractions were observed with the slag rather than slag flotation tailings. Thus, the maximum copper and iron extractions achieved with the slag were 26.0% and 62.5%, respectively, as opposed to the slag flotation tailings where the maximum copper and iron extractions were 13.5% and 48.0%, respectively.

The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption.

COMPARATIVE RESULTS OF COPPER FLOTATION FROM SMELTER SLAG
Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once more for production of cop- per cathodes and the rough flotation tailings go to the flotation tailing dump. Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%.
