copper copper slag recovery equipment

  • Copper slag selection process and equipment Prominer

    There are usually only two types of recovery equipment for the copper in the copper slag of the beneficiation equipment, one is the more common jig equipment, and the other is the shaker. The jig is mainly used to recover copper smelting slag with uneven thickness, and the beneficiation equipment shaker is mainly used to recover fine copper.

  • Recovery of Copper from Reverberatory Copper Slag and

    concentrate, various mining operations have initiated the recovery of copper from dumped slag. 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.

  • 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 & zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.

  • [PDF] Recovery of copper from the copper slag and

    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 Recovery in Smelting Slag Recycling

    Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
