higher-grade copper slag concentrate at a cooling rate of 2 °C/min, and that a proper holding time was favorable for increasing the (molten) copper-containing phase. In order
Bavarder sur InternetIn this article, to improve the recovery of copper from copper slag by flotation process, industrial tests of the modification process involving addition of a composite additive into molten copper ...
Bavarder sur InternetSynopsis. This chapter deals with the production, chemical and physical properties and potential applications of copper slag (CS), as well as its associated environmental
Bavarder sur InternetAir-cooled copper slag has a dull black color and a glassy appearance. Granulated copper slag is more vesicular and porous and therefore has lower specific gravity and higher
Bavarder sur InternetIn this study, copper slag (CS) was investigated in detail. The leaching mechanisms of the heavy metals in CS were identified via a pH-dependent leaching test
Bavarder sur InternetA study of copper slag smelting indicates that there is value in characterizing copper slag with view of recovery of viable metals, especially iron.
Bavarder sur InternetAbstract. Air- cooled slag can be used as a granular material in a broad range of applications such as pavement subbase and base, railroad ballast, port and harbor
Bavarder sur InternetAbstract. This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high
Bavarder sur InternetRecovery of copper in concentrates from slags cooled in the induction furnace and ground for 30 minutes ranged from 87.1 to 96.2 percent with the best
Bavarder sur InternetThe typical phase composition of copper slags is summarised in Table 2.Many variations in the phase composition of copper slags can be observed because of some factors related to the pyrometallurgical process, such as characteristics of the copper mine processed, type of furnaces applied, type of additives (or flux) added, and type of
Bavarder sur InternetSlag cooling beneficiation, which uses the surface property differences of sulfide minerals and oxide minerals to enrich valuable elements in the slag concentrate, is the most widely used method in industry, and it can generally reduce the copper content in the tailings to 0.23 mass pct. [1,2,3,4,5] The separation of matte droplets could be
Bavarder sur InternetSome physical and mechanical properties of copper slag is shown in Table 2. Air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from a low of 2.8 to as high as 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate.
Bavarder sur InternetGlobally a large volume of copper slag (Table 1) is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [9].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [6].Table 1 illustrates the magnitude of slag
Bavarder sur InternetSynopsis. Consolidating 125 studies undertaken since 1989, the effects of copper slag (CS) used as sand on concrete properties are discussed. CS increases the consistence of concrete but, if uncontrolled, this may affect its stability. The setting times and early strength development are retarded.

Air-cooled slag is solidified under ambient conditions.Immediately after being discharged from the blast furnace, the molten blast furnace slag is dumped into cooling pits for air-cooling before further processing for
Bavarder sur InternetThe concrete Prisms were tested for flexure and the mix with 40% copper slag exhibited the maximum Flexural strength of 7.62 N/mm 2 with an increase in strength of 29.37% when compared to the nominal concrete. Mixes with higher % of copper slag (beyond 40%) showed a drastic decline in the flexural strength. •.
Bavarder sur InternetRecovery of copper in concentrates from slags cooled in the induction furnace and ground for 30 minutes ranged from 87.1 to 96.2 percent with the best recovery obtained on the highest grade slag sample. Copper content of the flotation tailings, which is the most important indicator, ranged from 0.26 to 0.39 percent.
Bavarder sur InternetIn this paper, the mineralogical characterization of typical copper slag supplied by the Tongling Nonferrous Metals Group China was performed based on x-ray fluorescence, x-ray diffraction, and scanning electron microscopy with energy dispersive spectroscopy. The results show that the dominant phases of the slag are fayalite, glassy
