Copper smelting is an intricate high‐temperature process that converts copper concentrates into purer metallic copper through a series of chemical and thermal reactions. Central to modern smelting ...

Copper smelting, a critical process in metal production, often leads to the generation of slag containing valuable metals. Traditionally, this slag has been discarded, causing environmental issues and ...

Copper smelting - a critical process in metal production - often generates slag, which contains valuable metals. This slag has historically been thrown away, causing harm to the environment and ...

Still Bright hopes its chemical process could help replace polluting copper smelters. Demand for copper is surging, as is pollution from its dirty production processes. The founders of one startup, ...

Research from Cranfield University sheds new light onto the transition from the Bronze Age to the Iron Age, showing how experimentation with iron-rich rocks by copper smelters may have sparked the ...

At a laboratory in Newark, New Jersey, a gray liquid swirls vigorously inside a reactor the size of a small watermelon. Here, scientists with the mining technology startup Still Bright are using a ...

The International Copper Study Group says copper production increased in the first half of 2025, and London-based Earth-i says the trend continues. Earth-i, in a late September press release, says ...
