Copper slag flotation process. 05-18-21; 79 Views; icon 0; The slag produced by copper pyrometallurgy in China is more than 10 million tons every year. The slag contains natural copper, a small amount of copper oxide and copper sulfide. Copper slag generally contains valuable elements such as iron, zinc and a small amount of copper with recycling value.

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. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 and 2017).

Thionocarbamates are the group of collectors that are mostly used for flotation of sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition of the ore. In this paper, the results of the study of application of thionocarbamates in copper slag flotation are presented. Chemical analysis of smelter slag sample obtained from …

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 FWCS appears a suitable raw material as iron source containing >59% Fe(2)O(3) mainly in the form of fayalite (Fe(2)SiO(4)) and magnetite (Fe(3)O(4)). The clinker products obtained using the FWCS from ...

because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption. The present work shows that digestion of the milled …

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.

The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment. Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper.

slow cooled copper slag. Greater understanding, improved performance "The best flotation performance was achieved with the 50:50 addition ratio of DSP 330 and SIBX, with a copper recovery of 92.4% for a head grade of 5.4% and a cut-off copper grade of 24-25%."

Flotation reagents have a complex behaviour in the beneficiation of base minerals in clayey ores. Interaction effects of reagents on the efficiency of copper flotation for a highly clayey low-grade sulphide ore were investigated using a central composite design. ... Hydrophobic-surface of copper from converter slag in the flotation system [J ...

The reasons this copper has not floated are probably the same as those posed earlier for the self-pulverising slag; namely insufficient reagent dosage or flotation time, or the difficulty in recovering certain size or shaped copper metal particles. ... Selectivity comparisonThe comparative copper flotation behaviour with respect to the (pilot ...

2017/02/08· 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 copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

It was found that the raw copper slag contained 2.30% Co, 5.27% Cu and 35.13% Fe. After flotation, a concentrate containing 0.88% Co was produced. The highest recovery of cobalt was obtained at pH 8 with a recovery of 38.37%. Sulfurization and flotation of copper smelter slag has potential in valorisation of slag and help to mitigate the ...

For an air-cooled slag at optimized conditions, 72% of copper was recovered in one stage flotation and a 12.6% copper concentrate was achieved. The best recovery efficiency was obtained when 30 g ...

The information will help in the flotation of copper smelter slag for better copper grade and recovery. 1. Introduction 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.

To achieve this goal, the phase of copper smelting slags was analyzed; then, based on the phase structure of copper slags, the flotation process was determined, and the effect of different variables (grinding time, sodium carbonate dosage, collector dosage and so on) on the flotation effect was systematically studied.
