The first metal mine in Australia was opened near Glen Osmond in South Australia in 1841, for silver-lead ore. It was followed by the Kapunda Mine for copper in 1844 and by the very signifi- cant Burra Mine, also for copper, in 1845 (Figure 1). ... carrying reducing quantities of copper, so that the slag rejected from the first melting process ...

The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation …

The environment downstream of Gulf Creek, a legacy copper mine in southeastern Australia, has been impacted by leachate and the stream channel is lined with algae coated in powder blue precipitates rich in copper (Cu) and zinc (Zn). The workings have been rehabilitated, with slag rich in Cu and Zn distributed over soil …

The total production figures of copper slag by country show that Chile had the highest amounts of copper slag in the last 20 years with 243 million tons, representing …

The copper losses in smelting slag in the RHF were more than 3% in 2006 and 2007. Thermodynamic models and viscosity models have been applied in the operation of Xstrata Copper Smelter in Australia. The theory of RHF key performance indicators has also been developed to reduce the copper losses in RHF slag.

In this research, a hydrometallurgical method for recovery of copper from copper rich converter slag is investigated. The main copper containing phases of the slag are cuprite (Cu 2 O), delafossite (CuFeO 2) and metallic copper (Cu).The study investigates the effect of particle size, temperature, acid concentration, agitation and …

The copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper …

In order to achieve single recovery of Fe, Cu and Si in copper slag and deep removal of impurities in products, the activated reduction combining directional oxidation are adopted to improve the separation limit of target components, which mineral constituent as well as chemical composition at different stages are investigated through …

CRRI suggests copper slag as replacement of river sand and fine aggregate in concrete. Addition of 30%–60% of copper slag as per Chandrasekhar and Chokshi would improve the characteristics of soil. Copper slag's grain size distribution curve is similar to that of medium sand Chandrasekhar and Chokshi .

The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte (a Cu–Fe–S–O melt) and silica-saturated iron silicate slag were determined at 1250–1350 °C, under ...

Nickel smelting slag contains valuable metals including nickel and copper. Failure to recycle these metals wastes resources, and disposal of nickel slag in stockpiles results in environmental pollution. Nickel slag recycling is important, and metals can be recovered from slag by flotation. However, considering the complex forms in which …

The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte and silica-saturated iron silicate slag were determined at 1523 K to 1623 K (1250 °C to 1350 °C), in controlled CO-CO2-SO2-Ar gas mixtures. The experiments were done in silica crucibles and a fixed partial pressure of sulfur dioxide for matte grades of …

During about 40 years of copper production, about 8 million tons of slag with an average Cu content of 1.67 wt%, 40–56 g/t Ag, 1 g/t Au and 0.05 wt% Mo as a metallurgical waste has been disposed of by a …

Slag dumps occur at several historical smelting sites in north Queensland, Australia. The microcrystalline slags contain primary slag phases, relict flux, ore and furnace materials and secondary weathering related minerals. Common primary slag phases are glass, Zn-rich fayalite (± Zn-rich kirschsteinite) and Zn-rich hedenbergite.

The distribution coefficients of Au (L m/s Au), Pt (L m/s Pt) and Pd (L m/s Pd) between matte and slag were approximately stable at 1000 when copper content in matte increased from 40 to 55 wt pct Cu, and then it decreased from around 1000 to 200 with increasing matte grade.

Metal value recoveries in extraction are the key issue for sustainability of metals. The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte (a Cu–Fe–S–O melt) and silica-saturated iron silicate slag were determined at 1250–1350 °C, under controlled oxygen and sulfur pressures and at fixed partial …

Figure 5 Imports of waste textiles into Australia by grade, 2020-21 Around 36,000 tonnes of material were imported into Australia that would be classified as ash5. This was nearly …

The reverberatory slag is produced from the reverberatory smelting furnace and usually produces the slag that is more dilute in copper of about 0.6% and is …

In Australia, the Copper Slag market is growing, fueled by its widespread use in construction and abrasive applications. Copper slag, a byproduct of copper production, …

(for example) copper slags, lead slags and, of particular interest to the Australian concrete industry, iron slags. ... The first attempt at an Australian Standard for slag was published in 1991 reflecting the relatively recent use of this material. The current Australian Standard is …

1. Introduction. Copper (Cu) is one of the most widely used metals in the world, alongside iron (Fe) and aluminum (Al). It is estimated that 22 million metric tons of Cu is mined globally in 2023 (Attwood, 2022).More than 80 % of Cu products worldwide are obtained through smelting (Zhang L. et al., 2024), forming various slags containing almost all …
