2016-8-2  Copper slag is a byproduct of the copper smelting industry. Generally, 2.0–3.0 tons of copper slag is generated per ton of copper produced in the whole process, depending on the properties of the copper sulfide concentrates and the operating conditions.1,2 It is estimated that approximately 12 million tons of copper slag is discharged into the environment annually in China.

Copper Smelting Slag Recovery- metalcess

Copper Smelting Slag. Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead & zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.
