• The Recovery of Copper from Smelting Slag by Flotation

    Feb 08, 2017· Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

  • Characteristics and utilisation of copper slag—a review

    Nov 01, 2003· A flotation scheme used at the Almalyk copper smelter for processing slags together with Cu–Mo ores was described, and ways to optimise the slag flotation process were examined (Sigedin et al., 1986). Results of the flotation of converter slag were presented, and the effect of the combined flotation of slags with the ores on the recovery of copper was also evaluated.

    Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%. Slag in RTB plants is processed in a facility that is not designed for slag processing but it is only adapted to these conditions. The obtained results are worser than the expected ones and testing that could improve them will continue. This shows the way of obtaining the flotation concentrate of smelter slag with

  • Ferric leaching of copper slag flotation tailings

    Jan 01, 2009· Slag flotation tailings contain Cu-bearing species, which are mostly occluded in the slag phase, unable to interact with the collector. The present studies the recovery of Cu from slag flotation tailings by a hydrometallurgical treatment based on the BRISA process (Palencia et al., 2002, Romero et al., 2003, Carranza et al., 2004). This process is based on indirect bioleaching, and
