Nov 30, 2008 Copper slag wastes, even if treated via processes such as flotation for metal recovery, still contain heavy metals with hazardous properties posing environmental risks for disposal. This study reports the potential use of flotation waste of a copper slag FWCS as iron source in the production of Portland cement clinker.
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 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 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.
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

This study reports the potential use of flotation waste of a copper slag FWCS as iron source in the production of Portland cement clinker.
The cumulative copper recoveries increased markedly to over 90, which represents a significant improvement in comparison to the recoveries obtained from the mill-float process. Sodium alkyl dithiophosphate, mercaptobenzothiazole FC7245 was found to be the secondary flotation reagent that gave the best copper recoveries.
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.
Oct 10, 2015 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 ...
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,
Nov 30, 2008 flotation waste of a copper slag FWCS as iron source in the production of Portland cement clinker. The FWCS appears a suitable raw material as iron source containing 59 Fe2O3 mainly in the form of fayalite Fe2SiO4 and magnetite Fe3O4. The clinker products obtained using the FWCS from the
Guo et al. 2016 developed a new technology to improve the beneficiation of copper and iron components from copper slag, by modifying the molten slag to promote the mineralization and grain growth of the valuable compounds. Results showed that, under the proper conditions, the copper grade of the rougher stage increased from 6,43 to 11,04 the iron recovery of magnetic separation
Jan 01, 2020 Various flotation reagents that are commonly used for copper flotation were identified, selected and used during the flotation test work in order to identify the best reagent best suited to float the copper slags. Potassium amyl xanthate PAX and Flotanol CO 7 were used in all tests as the primary collector and frother.
Feb 01, 2007 The second route was flotation of the slags, roasting of the flotation tailings with pyrite and leaching. The second route was found to be suitable for the treatment of the copper slag studied. In the flotation step, a copper concentrate containing approximately 11 Cu was produced with a 77 recovery while 93 of the cobalt stayed in the tailings.
Key words Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another
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.
Copper-Gold Flotation Process at larger capacity making it feasible of treating available lower grade copper-gold ore and after exhausting this copper-gold ore the Company will operate the 3,000 MTPD Carbon-In-Pulp CIP Plant to process the remaining gold ore. This CIP Plant operation alone will be much lower than the allowed 10,000 MTPD.
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 ...
Apr 05, 2015 The content of copper in the flotation tailings directly depends on fragmentation rate Figure 1. Expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.5-0.9, and in the case of cooling in pots, from 0.22 to 0.35 Cu. Fig. 1. The effect of fragmentation rate on the slag flotation 6
In this study the effect of mixtures of copper slag and flotation tailings from copper mine Bor, Serbia on the flotation results of copper recovery and flotation kinetics parameters in a batch flotation cell has been investigated. By simultaneous adding old flotation tailings in the ball mill at the rate of 9, it is possible to increase copper recovery for about 20.
Copper loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1-3 . At present, the electric slag cleaning furnace is used for the recovery of copper from slag. However, due to low recovery efficiency of electric furnace along with high consumption of electrical energy and water, selection of a method to enable minimum energy consumption and maximum recovery of copper ...
the copper content were produced during that period, as illustrated by Figure 1. According to the RTB Bor archive and the pub-lished data 19, the average copper content in the processed ores varied from 4, at the very beginning to 0.6 at the end of the Old Flotation Plant works. Copper content in the flotation tailings had been
