Characterization and recovery of copper values from discarded slag .These oxide and sulfide phases of copper are mostly present within the slag phase and to some extent the slag is also embedded inside the oxide and sulfide phases. The recovery of copper values from the discarded slag has been explored by applying a flotation technique using conventional sodium isopropyl xanthate.Characterization and recovery of copper values from discarded slag2004). In the Black Sea Cop- per Works, Turkey, about 100 000 tons of slag are treated annually by the flotation process, after being crushed and ground, to recover additional copper values (Arslan & Ars- lan 2002). However, it has been estimated that a copper recovery higher than 80% is required to make such a process.
Management of copper pyrometallurgical slags: giving . - SAIMMare presented. Since, final copper slag contain around 1% of copper, its recovery from the slag could be economically accepted if no expensive treatments are found, such as techniques mixing pyro and hydrometallurgical processes or concentration by flotation as it has been established in some concentration plants.Paper - Slag Valorisation Symposiumconsequences. The copper industry as an example currently process ores containing less than 1% copper with discard of 99% of the weight of this material including overburden, tailings and slag from mining, flotation and smelting operations. The primary metal production industry has given much attention to the improved.
