The Iberian Pyrite Belt (IPB), SW Spain and Portugal, contains about 100 abandoned mine wastes and galleries that release acid mine drainages (AMD) to the Tinto and Odiel rivers. In situ passive remediation technologies are especially suitable to remediate the drainages of these orphan sites. However, traditional remediation …

Abstract The Iberian Pyrite Belt (IPB) has, over the past decade, been an area of renewed mining activity and scientific research that has resulted in a wealth of new data and new geological and metallogenic concepts that are succinctly presented in this Thematic Issue. The reason for this interest in the IPB, which forms part of the …
The Iberian Pyrite Belt (IPB), ... There are several works that refer the application of mine wastes, namely from coal and metals exploitation or beneficiation [2]. The pavement and construction sectors appear as key markets for such reuse or recycle. Particularly, since the 1970s has being growing the use of supplementary cementitious ...

THE IBERIAN PYRITE BELT (IPB) Covers a territory of 240 km by 35 km in Spain and Portugal Estimated current resources are over 1,500 million tonnes of primary massive sulphides Mined more than 5,000 years, having over 200
Our results suggest that the emplacement of the pyrite belt was both pre- and syncollisional, and was initiated primarily by lithospheric delamination related to tectonic escape and crustal thinning of the lower plate. In this scenario, protracted magmatism occurred in both subaerial and subaqueous settings from c. 370 to 338 Ma.

[EN] The volcanism in the Iberian Pyrite Belt migrated from the present day west/southwest to the east/northeast during Devonian/Carboniferous times. Evidence is here discussed based in U-Pb zircon ages of felsic volcanic and plutonic rocks, bounded by enclosed sediments and their biostratigraphic ages, together with hosted massive sulphides ...

The occurrence and distribution of gold in the massive sulfide orebodies of the upper Palaeozoic volcano-sedimentary environment of the SW Iberian Pyrite Belt have long been assumed to be quite uniform. Recent investigations in several working mines indicate that the gold content of the ores varies between ore types, and is controlled by physico …
