Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt. copper and 40 wt. iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica. These exist in copper slag mainly in the form of fayalite 2FeO SiO2.

Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
Copper Slag is an aggressive abrasive primarily used for the surface preparation of metals and concrete surfaces. Its bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action-increasing production rates. Low cost option.

Copper is present in a smelting slag from Teniente Converter TC in the form of mecha-nically entrained matte inclusions and dissolved copper. Copper recovery from the slag requires magnetite reduction to liberate matte inclusions and create conditions for co-reduction of dissolved cuprous oxide. Efficiency of copper recovery from the slag in an
Copper Smelting Slag Recovery- - Metalcess. 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 amp zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.
