Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

The first isotopic evidence of Early Iron Age lead ore exploitation in the Silesian‐Krakow upland, Poland: a provenance study of Lusatian culture lead ornaments

Archaeometry, Volume 67, Issue 3, Page 552-569, June 2025.
Abstract The Bronze and Early Iron Ages witnessed a significant increase in trade relations driven by the search for valuable metals. This paper presents new insights into the use of galena from the Silesia and Krakow Upland region in southern Poland, known as the ‘Olkusz ore deposits’, within the context of metal ores in prehistoric Europe.

Low‐Level Urban Anthropogenic Sources Contribute to Strong Aerosol Light Absorption on the South African Highveld

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 10, 28 May 2025.
Abstract This study investigated the chemical composition and shortwave absorption coefficient, βabs(λ), of aerosols collected from sites on the Highveld, a major industrial and highly polluted region of South Africa. Local anthropogenic mineral dust was found to be the dominant chemical component, accounting for (53 ± 14)% of the aerosol mass ...
