This book outlines how Rio Tinto redesigned and rebuilt relationships with communities after the rejection of the company during Bougainville's Civil War. Glynn Cochrane recalls how he and colleagues utilized their training as social anthropologists to help the company to earn an industry leadership reputation and competitive business advantage by establishing the case for long-term, on the ground, smoke-in-the-eyes interaction with people in local communities around the world, despite the appeal of maximal efficiency techniques and quicker, easier answers. Instead of using ready-made, formulaic toolkits, Rio Tinto relied on community practitioners to try to accommodate local preferences and cultural differences. This volume provides a step-by-step account of how mining companies can use social anthropological and ethnographic insights to design ways of working with local communities, especially in times of upheaval.

An investigation into one of the largest and most lucrative mineral mining companies in the world, Rio Tinto, Extraction Politics reveals how the company constructs a presence in the places it operates and shapes meanings and orientations toward the environment. Taking readers on a “rhetorical pilgrimage” across the American Southwest, Nicholas Paliewicz shows how Rio Tinto creates adaptable corporate identities. From Ronald Reagan’s frontiersman advertisements for the Borax Mine in California to the pioneer Mormon persona at Bingham Canyon Mine in Salt Lake City and the folksy, paternalistic perspective toward the San Carlos Apache at the proposed mine at Oak Flat, Arizona, the company appropriates local history to embed itself as a valued member of the public—without having to settle in those ecological communities and bear the costs of extraction. This does not occur without resistance, however. Paliewicz also shows how activists use these same tactics to expose Rio Tinto as an exploitative, colonialist polluter. In an era of surging demand for dwindling supplies of minerals and metals, this book previews what the future of extractivism may look like. Extraction Politics will appeal to scholars and students of environmental communication and activist politics as well as general readers interested in the climate crisis.

Productive ways of thinking about work have emerged from the recent engagement between scholars in employment relations and human geography without any sustained attention to the spatiality of the labour process itself. Arguing that where work literally ‘takes place’ is important, this article explores the spatial nature of the labour process through an examination of automation in one of the world’s largest transnational mining companies, Rio Tinto. To read the labour process in spatial terms, work must be understood in the context of global production networks, the peculiarities of national ‘space economies’ and arguments about the claimed ‘hyper-mobility’ of globalized capital as well as labour geography itself. In this case, automation and a reworking of the geography of the labour process in an industry often seen as constrained by physical geography have implications for assessing labour’s agency and power amid more general changes to the spatiality of work.

Titania slag, produced from smelting placer ilmenite concentrates and used as a feedstock for TiO2 pigment production, contains low levels of radioactivity due to thorium and uranium. This study investigated the distribution and speciation of thorium in Rio Tinto Chloride Slag (RTCS), which contains an average of 170 ppm Th and 16 ppm U, using a variety of analytical methods from powder X-ray diffraction (PXRD) analysis to bulk and laser ablation inductively coupled plasma mass spectrometry (ICP-MS and LA-ICP-MS), electron microprobe analysis (EMPA), quantitative evaluation of materials by scanning electron microscopy (QEMSCAN), Raman spectroscopy, microbeam synchrotron X-ray fluorescence (µsXRF) mapping, synchrotron Laue X-ray diffraction (LXRD) and synchrotron X-ray absorption spectroscopy (XAS). Our data demonstrate that ∼99.4% of Th in the RTCS is hosted by a chevkinite-like Th-REE-Ti aluminosilicate containing an average of 8.05±0.64 wt.% ThO2. The Th-REE-Ti aluminosilicate occurs as acicular (∼0.3 × 12 µm) or tabular (∼5 × 15 µm) crystals in association with a Th-bearing aluminosilicate glass (0.41±0.35 wt.% ThO2) as infillings either in interstitials or along the fractures of the main Ti-Fe oxides of the sassite-ferropseudobrookite solid-solution series. The Th-REE-Ti aluminosilicate and associated Th-bearing aluminosilicate glass formed probably during the quenching stage of the titania slag production. LA-ICP-MS analyses and µsXRF mapping show that the main Ti-Fe oxides in the RTCS contain an average of only 0.32±0.60 ppm Th. Future pyrometallurgy operations that utilise Th- and U-bearing heavy mineral sands must consider their environmental effects and mitigate radioactivity. In addition, preferential acid dissolution of the Th-REE-Ti aluminosilicate in RTCS and other titania slags may be used to recover Th and REE for dual environmental and economic benefits.

This work presents the results of a geochemical and geophysical characterization of the Monte Romero and La Naya mine ponds, belonging to the Cueva de la Mora and Riotinto mine districts, respectively, based on mineralogical, geochemical and geophysical techniques. In order to obtain a representative environmental characterization, two deposits showing different mineralogies, physico-chemical parameters, chemical compositions of tailings and pond conditions were selected. Monte Romero mine tailings showed an upper level mainly composed of silicates and a deeper level mainly composed of sulfides and barite. The toxic metal content was different in both levels but high enough to exceed the regional legal concentration limits for agricultural soils. An electrical resistivity tomography survey revealed a homogeneous upper unit (3 m thickness), which displayed low resistivity values, corresponding to water-saturated silt and clay materials with an abundance of sulfides which was interpreted as the pond infilling. The La Naya mine pond presented a homogeneous mineralogical composition made up of quartz as the main mineral and chlorite-smectite and jarosite as accessory phases. The absence of sulfide phases and the low contents of metal elements are directly related to the reworking processes of the sludge dumped in this pond. The geophysical survey revealed that the pond infilling did not have a constant thickness, but ranged between 15 and 20 m. An inner groundwater flow in the infilling was recognized. The low resistivity values allowed the presence of acid waters and related subsurface flows to be identified in both mine ponds, but no acid water drainage occurred across their vessels. When compared to the Aznalcóllar tailings spill, the La Naya pond is large enough to release a similar amount of sludge, but of a very low metal content. The Monte Romero sludge displays a similar, potentially toxic metal content to the Aznalcóllar sludge, but its size is significantly smaller.

A geochronology study using U–Pb isotope dilution TIMS analyses of zircon has been conducted to determine the ages of volcanic-associated massive sulfide (VMS) deposits in the Iberian Pyrite Belt (IPB), the world's most prolific VMS province. Ages have been determined for host rocks to four VMS systems that span the IPB: the giant Rio Tinto and Aljustrel districts in the central region, Lagoa Salgada to the west, and Las Cruces to the east. A sample of chloritized quartz porphyritic dacite/rhyolite in the footwall of the San Dionisio massive sulfide deposit of the Rio Tinto district is 349.76±0.90 Ma. This is taken as the best age estimate of the mineralization in the Rio Tinto district, probably the world's largest volcanogenic massive sulfide system. Two xenocrystic zircons from the same sample yielded 207Pb/206Pb ages of 414 and 416 Ma, which provide a minimum estimate for the age of the inherited component. A biotite tonalite from the Campofrio area, 3.5 km north of the center of the Rio Tinto district, is chemically similar to the felsic host rock protolith at Rio Tinto. The Campofrio sample has an age of 346.26±0.81 Ma, slightly younger and outside of the 2σ error for the Rio Tinto age; therefore, this phase of this intrusion was not a heat source for the hydrothermal system that formed the deposits of the Rio Tinto district. The Campofrio sample also has three zircon analyses with 207Pb/206Pb minimum ages of 534, 536, and 985 Ma, indicating inheritance from Ordovician and Neoproterozoic sources. In the Aljustrel VMS district, a U–Pb zircon age of 352.9±1.9 Ma characterizes the altered Green Tuff host rock of the Algares deposit, which is slightly older than the Rio Tinto age. Two zircons with 207Pb/206Pb ages of 531 and 571 Ma from this sample indicate inheritance from a Cambrian or older source. The age of mineralization at Lagoa Salgada is given by essentially identical ages of 356.21±0.73 and 356.4±0.8 Ma, for footwall and hanging wall samples, respectively. The hanging wall sample has two zircon analyses with 207Pb/206Pb ages of 464 and 466 Ma, indicating inheritance from an Ordovician or older source. The age for an altered dacite tuff sample from the hanging wall of the Las Cruces deposit is 353.97±0.69 Ma. One zircon analysis from the Las Cruces sample has a 207Pb/206Pb age of 1048 Ma, indicating inheritance from a Neoproterozoic source. These U–Pb ages refine the IPB geochronology provided by previous studies, and they suggest that either volcanism progressed toward the center of the IPB, or that volcanism was broadly static and the strata were progressively rifted to the margins during transtensional basin formation. The zircon inheritance provides direct evidence for Proterozoic to Ordovician sources, reflecting either basement rocks beneath the Phyllite–Quartzite Group during VMS formation in late Tournaisian times, or a Proterozoic to Ordovician detrital component in Phyllite–Quartzite Group source rocks. The presence of an older crustal component is consistent with VMS formation during rift development at a continental margin.

We present the first platinum group elements (PGE) data on seven massive sulfide deposits in the Iberian Pyrite Belt (IPB), one of the world largest massive sulfide provinces. Some of these deposits can contain significant PGE values. The highest PGE values were identified in the Cu-rich stockwork ores of the Aguas Teñidas Este (Σ PGE 350 ppb) and the Neves Corvo (Σ PGE 203 ppb) deposits. Chondrite normalized PGE patterns and Pd/Pt and Pd/Ir ratios in the IPB massive, and stockwork ores are consistent with the leaching of the PGE from the underlying rock sequence.[PUBLICATION ABSTRACT]

Life as known here on Earth exchanges energy and materials with the environment. Life forms grow, develop, produce waste products, and reproduce, storing genetic information in DNA and RNA and passing it from one generation to the next. Life evolves, adapting to changes in the environment and changing the environment in return. The basic unit of living things is the cell. Life is based on the chemistry of carbon and requires liquid water. This article discusses the following topics relating to astrobiology: what exactly it means to be alive; what astrobiologists do; extreme environments; and extreme environments on other planets.
