Metals | Highly Cited Papers from 2023 in the “Extractive Metallurgy” Section


The “Extractive Metallurgy” Section of Metals (ISSN: 2075-4701) focuses on the latest advances in the extraction and recovery of metals from primary ores and secondary resources. This Section aims to promote a deeper understanding of metallurgical processes through research on innovative physical, chemical, and thermochemical methods.

Key areas of interest include pyrometallurgy, hydrometallurgy, electrometallurgy, bioleaching, solvent extraction, recycling of metallic wastes, process optimization, and the environmental aspects of metal extraction.

We welcome contributions ranging from fundamental research to industrial applications, particularly those offering sustainable and energy-efficient solutions in the production of critical, strategic, and base metals.

As all papers published in Metals are open access, readers have free and unlimited access to the full texts. We invite you to explore the following highly cited papers from 2023:
