Mining metal from waste

Geology Today, Volume 42, Issue 1, Page 15-26, January/February 2026.
With the transition to a low carbon future and increasing technological applications, the global demand for metals will continue to rise into the foreseeable future. However, primary ore deposits are finite, and to continue production, lower grade and more complex ore deposits need to be discovered, evaluated and exploited, with increasing exploration ...

Contents of deposits from the archaeological site of Sobolów in Bochnia—A contribution to prehistoric foundry activity

Archaeometry, Volume 67, Issue 5, Page 1081-1097, October 2025.
Abstract In the Sobolów area, three hoards of the Hallstatt period were discovered, containing ornaments, waste and scrap of tin–lead–bronze alloy, with iron objects in close proximity, possibly indicating the existence of a foundry workshop. They were accompanied by glass beads, an indicator of the settlement of the Lusatian EB‐Ha Culture, found ...

Mineralization at Different Structural Levels in the Crust

Acta Geologica Sinica - English Edition, Volume 99, Issue 4, Page 1042-1058, August 2025.
Abstract Metallogenic research on structural levels can reveal vertical patterns of mineralization and facilitate the deep exploration of economic minerals. However, research focusing on the correlation between structural levels and mineralization remains limited.

Gejiu tin polymetallic ore-field: deposit model and discussion for several points concerned [PDF]

, 2008
Gejiu is the largest polymetallic tin ore-field over the world. It has been known as the Yanshanian ranite-related deposit for long time, but recently some researchers argued that it is a syngenetic deposit formed by marine exhalation or it is a basalt ...

Geological Knowledge‐Guided Dual‐Branch Deep Learning Model for Identification of Geochemical Anomalies Related to Mineralization

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Geochemical survey data are a type of spatial big data that play an increasingly significant role in mineral exploration. One challenge in the era of big data is how to mine geochemical data in support of mineral exploration. In this study, based on a generative adversarial network framework, we proposed an unsupervised spatial–spectrum dual ...
