- Copper Machine Diagram Slag Waste
The copper smelting industry generates copper slag as its primary solid waste (Tian et al., 2021).The pyrometallurgical process extracts approximately 80% of the copper (Zuo et al., 2022), producing 2–3 tons of copper slag for every 1 ton of copper (Qu et al., 2023).According to statistics, global copper slag emissions in 2022 alone reached 35.2 million …
