Experimental and thermodynamic investigations were carried out to understand the reaction and separation process and its correlation with smelting temperature, modified basicity …
Recycling copper slag can make a positive contribution because there is significant energy invested in these slags, and it contains various metals possible to be recovered. …
Industrial sludge is generated at a rate of 100 metric tons/day, from a copper slag recycling plant. Copper slag is widely used as an abrasive media to remove rust, old coating and other impurities in dry abrasive blasting due to its high hardness (6-7 Mohs), high density (2.8-3.8 g/cm3) and low free silica content.
A field experiment was conducted to study migration of the elements from the copper smelting slag recycling waste into high-moor peat and lawn grasses.
Extracting valuable metal is a common way of recycling copper pyrometallurgical solid waste (CPSW). However, its environmental effects are still unclear. This paper adopts a cradle-to-gate life cycle assessment to assess the impacts of recycling three main types of CPSW (smelting slag, copper ash, and anode slime).
Cement, one of the main components of concrete, poses environmental risks, accounting for 7% of total global carbon emissions. To alleviate the environmental hazards related to cement manufacturing, supplementary cementitious materials (SCM) are employed to reduce the usage of cement in concrete. One SCM used is copper slag (CS). In this study, a life cycle …
The use of copper slag as a pozzolanic material for a partial substitute for ordinary Portland cement and its effects on the hydration reactions and properties of mortar and concrete have been reported in several publications (Al-Jabri et al., 2006, Taha et al., 2007, Malhotra, 1993, Tixier et al., 1997, Ariño and Mobasher, 1999, Douglas and Mainwaring, 1986, Deja and …
Copper Slag (CS) is a solid waste produced during the industrial smelting of copper (Gorai et al., 2003).The current pyrometallurgical copper smelting process is mainly through the Ausmet furnace (Fig. 1); the furnace slag goes through the flotation process to obtain copper matter, yielding a composition of CS corresponding to 30–40 % of Fe, 15–20 % of Si, less than …

Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica. These exist in copper slag mainly in the form of fayalite (2FeO ·SiO 2).
