Enhancing the flotation recovery of copper minerals in smelter slags
The slags produced from the NCS furnaces (TSL furnace, copper converter, reverberatory furnace) contain copper ranging between 0.8 to 5% w/w. Due to this high content of copper, the slags are milled and floated to recover the copper. The main drawback in the current process is that the final flotation tailings grades are in excess of Publication Publication Date Title. US3682623A Copper refining process.

Characterization and Recovery of Copper from Converter Copper
Converter copper slag can be viewed as an important secondary resource for valuable metals, considering its high commercial value. The current research investigates the recycling of copper by a combination of theoretical and experimental methods. Based on a modified Stokes equation, it was determined that copper droplets in the molten slag To determine slag properties and the factors influencing these properties for optimization of operating conditions in the copper flash smelting process, the composition and microstructures of the quenched smelting and converting slags have been analyzed. Thermodynamic software FactSage 8.2 has been used to investigate the effects of matte Metals Free Full-Text Control of Copper Content in Flash

It also describes strategies for minimizing the amount of copper lost from their disposal. Cu smelters produce two slags: smelting furnace slag with 1–2% Cu and converter slag with 4–8% CuThe microstructure of slags was studied through a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS), and the results are shown in Fig. 2.As is shown in Fig. 2 (a), five different particles can be observed. According to the EDS in Fig. 2 (b) and (c), the valuable sulfide predominantly comprises Copper recovery from copper slags through flotation

Investigation of Copper Losses to Synthetic Slag at Springer
With the addition of 6% CC for 2 h at 1250°C under PO 2 = 10 −9 atm, 0.34% Cu was obtained as the lowest copper content in the slag for experiments with flash furnace slags, while the minimum copper content for experiments with synthetic slags was 0.43% Cu under the same conditions. This difference can be considered due to the The slags included a moderately reduced low copper slag, a more oxidised high copper slag, a very reduced low copper self-pulverising slag, and a moderately reduced low copper Escondida slag. The slags varied in copper content from 5.2% to 15.1% Cu. The dominant form of copper in all the slags was metallic copper. A simple.

Recovery of iron and removal of hazardous elements from waste copper
Copper slag is inevitably produced by slag cleaning furnaces as a final byproduct; this type of setup is widely used in the sand-blasting industry. Although waste copper slag has several advantages as a raw material for utilization in various applications, hazardous elements (e.g., As, Pb, Bi, Sb) are dispersed physicochemically within the slag.The utilization of copper smelting slags has been investigated broadly (Fan et al. 2018;Gorai and Jana, 2003;Košir et al. 2021;Lemougna et al. 2020;Shi et al. 2008;Wang and Erdenebold, 2020), butAn Overview of Recovery of Metals from Slags ResearchGate

Recovery of Cu-Fe Alloy from Copper Smelting Slag
Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 wt% Cu and 35–45 wt% Fe equivalents to those in the copper and iron ores, respectively. Most of the research was focused on the recovery of iron from the The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and Chemical Composition Data of the Main Stages of Copper
