Key words Copper cobalt slag roasting pyrite copper concentrate 1 Introduction Significant amounts of copper cobalt and nickel can be obtained from copper slags which are produced in the thousands of tons per year in copper smelters Very different methods were used to recover metals from the copper converter slags
The analysis of highly reduced slags has shown that it is possible to remove virtually all of the cobalt and nickel from the olivine in the slag Nickelcopper converter slag B 32 MVA Largescale testwork on converter slag was conducted during 1994 on a 32 MVA DCarc furnace operating at a
Production of copper concentrate by flotation of smelter slag has started in 2001 Flotation concentrate goes to the Copepr Smelter once more for production of copper cathodes and the rough flotation tailings go to the flotation tailing dump Copper recoveries in the flotation process of smelter slag reaches the value of about 45 50

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
Sep 11 2009 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 SIX as the collector
