    15/1/2017· In this work, a new innovative slag cleaning technique was presented to economically and environmentally friendly recover valuable metals from cobalt-bearing copper smelter slag. CaSO 4 -rich gypsum waste was used as sulfurizing agent to efficiently and selectively sulfurize and recover valuable metals lost in the slag at reductive atmosphere.

    1/11/2003· The recovery of copper by flotation method from secondary copper slag is an alternate route (Osborn et al., 1990). Partial enrichment of Sn and Ni is also possible by this method. 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 ).
