Copper Tailing - an overview ScienceDirect Topics
Copper tailing is the waste rock remaining after ore has been processed to remove the copper. It is usually pulverized to the size of fine sand. It has relatively high specific gravity and primarily consists of silica in its composition.

COMPARATIVE RESULTS OF COPPER FLOTATION FROM
2013-11-26 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%.
