The recovery of copper from copper smelter slag utilizing flotation has been studied. A copper smelter slag from the Wang Jiaqiao smelter in Yunnan Province of china, containing 2.76 Cu, 44.41 Fe, 2.34 Zn and 18.4gt Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined.
Nov 30, 2008 flotation wastes of copper slag FWCS can be readily utilised as cement raw material due to its availability in large quantities at low cost with the further significant benefits for waste managementenvironmental practices of the FWCS and the reduced production and processing costs for cement raw materials.
Oct 10, 2015 Copper slag is produced during pyrometallurgical production of copper from copper ores. For every tone of metal production about 2.2 t of slag is generated. Dumping or disposal of such huge quantities of slag cause environmental and space problems.
flotation tests which were performed on slag samples from three different sources TSL furnace, copper converters, reverberatory furnace to recover the copper minerals. A range of commercial flotation reagents including xanthates, dithiophosphates, mercaptobenzothiazole,
The information will help in the flotation of copper smelter slag for better copper grade and recovery. Abstract Present work focuses on the differences in the performances obtained in the froth flotation of copper smelter slag with multiple collector viz. sodium iso-propyl xanthate SIPX, sodium di-ethyl dithiophosphate DTP and alkyl hydroxamate at various dosages.
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.
Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...
Copper smelters produce large amounts of copper slag or copper flotation waste and the dumping of these quantities of copper slag causes economic, environmental and space problems. The aim of this study was to perform a laboratory investigation to assess the feasibility of immobilizing the heavy metals contained in copper flotation waste.
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 cop-per 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.
Flotation is an important technology to recover copper from copper slag. There are a few industrial flotation facilities for treatment of copper slag, such as Magma Copper San Manual facility, USA, Altonorte Flotation Plant, Chile, Outokumpu facility, Finland,
The recovery of copper from smeltery furnace slag by flotation has been studied. By analysis the slag containing 1.61 copper and 27.80gt silver is available to recovery. The effective factors such as particle size, the amount and type of collector were examined. The combination of the collectors was also examined. With the process utilized in this work, a copper concentrate of 26.47 Cu with ...
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.

flotation of slag tailings using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. However, the maximum copper extraction attained with the slag was modest at about 63, whereas that obtained with the slag flotation tailings was as low as 33 Urosevic et al., 2015. Accordingly, the objective

Cu is the most important component in Cu slag, which is usually recovered by flotation. However, the crystalline state of Cu slag is not conducive to flotation, which limits the recovery of Cu. This study investigated the effect of Na2CO3 on the crystalline state of Cu slag and the recovery of Cu by flotation. The mechanism was investigated by thermodynamic, viscosity, X-ray diffraction XRD ...
of slag per year, the copper recovery re-mained low 50 10. The reason for this is the presence of 15-20 of copper oxide in slag and concentrated sulphide copper in the size classes below 38 m 11. Therefore, in the tailings from the flotation of slag, copper lags whose concentration is
Jul 22, 2019 Recover Copper from Reverberatory Furnace Slag. Laboratory and pilot plant investigations have indicated that copper recoveries of 50 can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic ...
Optimization of the flotation of copper smelter slags from contain copper with the content ranging between 08 to 5 copper The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant Slag Mill Plant for liberation and recovery of copper This focuses on optimizing.

Mar 11, 2018 The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4 , and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2 concentration can increase the sulphidizing effect of copper oxide, while Fe 3ampx2b sup inhibits the sulphidizing effect.
