#0183;#32;Abstract. 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 copperbearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.
Tailings from flotation of copper slag are a second RCRA special waste. Read more. Patent US Recovery of metal values from copper slag A hydrometallurgical process for treating slag material, especially copper smelter Flotation processes have had only marginal success in the recovery of the values
#0183;#32;Lowest copper recoveries were obtained with alkyl hydroxamate in single collector floation performance. It has been reported that the alkyl hydroxamate is not very selective for sulphide flotation. In case of copper slag most of the copper occur in the form of copper sulphide and shows very low response with alkyl hydroxamate.

#0183;#32;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 CuMo ores was described, and ways to optimise the slag flotation process were examined ( Sigedin et al., 1986 ).
Flotation was selected as a process for processing the slag with the aim of recovering copper. Flotation test showed that the recovery rate of copper depends on portion of fine grinding,
The copper slag used in the experiments is a byproduct generated during the cleaning of electric furnace slag and rening of copper in Tongling Nonferrous Metals Group Holding Co., Ltd (Tongling, China). As shown in Table1, the main chemical compositions contained in the waste slag are wt. %
For an aircooled slag at optimized conditions, 72% of copper was recovered in one stage flotation and a % copper concentrate was achieved. The best recovery efficiency was obtained when 30 g

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 % Cu, % Fe, % Zn and /t Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined.
leaching of copper from copper slag is shown in Figure 1. RESULTS AND DISCUSSION Table I gives the chemical composition of the copper slag; the results are obtained by using Xray fluorescence analysis. It can be observed from the analysis that iron, silicon and calcium are the major constituents. Table I. Chemical analysis of copper slag.
copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. in recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as collect early, loss early and more crushing and less grinding.
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 % Cu, % Fe, % Zn and /t Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined.
Copper recoveries in the flotation process of smelter slag reaches the value of about 45 50%. Slag in RTB plants is processed in a facility that is not designed for slag processing but it is only adapted to these conditions. The obtained results are worser than the expected ones and testing that could improve them will continue. This paper
higher absorption capacity than aircooled copper slag. The granulated copper slag is made up of regularly shaped angular particles, mostly between and mm3. Slags produced during pyrometallurgical processes have been traditionally considered as a waste3. In the case of copper extraction processes, it has been estimated that for every
Copper slag is a byproduct formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top. The molten copper slag is then drained off and quenched with water or left in the air to cool. In Singapore, treated and processed copper slag (Mohs Hardness 6) is imported from various
