Lithium Extraction in Argentina: a Case Study on the Social and Environmental Impacts
Lithium extraction in Argentina: a case study on the social and environmental impacts Pía Marchegiani, Jasmin Höglund Hellgren and Leandro Gómez. Executive summary The global demand for lithium has grown significantly over recent years and is expected to grow further due to its use in batteries for different products. Lithium is used in smaller electronic devices such as mobile phones and laptops but also for larger batteries found in electric vehicles and mobility vehicles. This growing demand has generated a series of policy responses in different countries in the southern cone triangle (Argentina, Bolivia and Chile), which together hold around 80 per cent of the world’s lithium salt brine reserves in their salt flats in the Puna area. Although Argentina has been extracting lithium since 1997, for a long time there was only one lithium-producing project in the country. In recent years, Argentina has experienced increased interest in lithium mining activities. In 2016, it was the most dynamic lithium producing country in the world, increasing production from 11 per cent to 16 per cent of the global market (Telam, 2017). There are now around 46 different projects of lithium extraction at different stages. However, little consideration has been given to the local impacts of lithium extraction considering human rights and the social and environmental sustainability of the projects. With this in mind, the current study seeks to contribute to an increased understanding of the potential and actual impacts of lithium extraction on local communities, providing insights from local perspectives to be considered in the wider discussion of sustainability, green technology and climate change. -

Solution Deposition of a Bournonite Cupbsbs3 Semiconductor Thin Film from the Dissolution of Bulk Materials with a Thiol-Amine Sol- Vent Mixture Kristopher M
Solution Deposition of a Bournonite CuPbSbS3 Semiconductor Thin Film from the Dissolution of Bulk Materials with a Thiol-Amine Sol- vent Mixture Kristopher M. Koskela, Brent C. Melot, and Richard L. Brutchey* Department of Chemistry, University of Southern California, Los Angeles, CA 90089, United States ABSTRACT: There is considerable interest in the exploration of new solar absorbers that are environmentally stable, absorb through the visible, and possess a polar crystal structure. Bournonite CuPbSbS3 is a naturally occurring sulfosalt mineral that crys- tallizes in the non-centrosymmetric Pmn21 space group and possesses an optimal band gap for single junction solar cells; however, the synthetic literature on this quaternary semiconductor is sparse and it has yet to be deposited and studied as a thin film. Here we describe the ability of a binary thiol-amine solvent mixture to dissolve the bulk bournonite mineral as well as inexpensive bulk CuO, PbO, and Sb2S3 precursors at room temperature and ambient pressure to generate an ink. The synthetic compound ink derived from the dissolution of the bulk binary precursors in the right stoichiometric ratios yields phase-pure thin films of CuPbSbS3 upon solution deposition and annealing. The resulting semiconductor thin films possess a direct optical band gap of 1.24 eV, an absorp- tion coefficient ~105 cm–1 through the visible, mobilities of 0.01-2.4 cm2 (V•s)–1, and carrier concentrations of 1018 – 1020 cm–3. These favorable optoelectronic properties suggest CuPbSbS3 thin films are excellent -

Global Lithium Sources—Industrial Use and Future in the Electric Vehicle Industry: a Review

The different industrial uses of lithium are discussed in this review along with a compilation of the locations of the main geological sources of lithium. An emphasis is placed on lithium’s use in lithium ion batteries and their use in the electric vehicle industry. The electric vehicle market is driving new demand for lithium resources. The expected scale-up in this sector will put pressure on current lithium supplies. The European Union has a burgeoning demand for lithium and is the second largest consumer of lithium resources. Currently, only 1–2% of worldwide lithium is produced in the European Union (Portugal). There are several lithium mineralisations scattered across Europe, the majority of which are currently undergoing mining feasibility studies. The increasing cost of lithium is driving a new global mining boom and should see many of Europe’s mineralisation’s becoming economic. The information given in this paper is a source of contextual information that can be used to support the European Union’s drive towards a low carbon economy and to develop the field of research. -
Mercury's Hollows: Chalcogenide Pyro
44th Lunar and Planetary Science Conference (2013) 2840.pdf MERCURY’S HOLLOWS: CHALCOGENIDE PYRO-THERMOKARST ANALOG OF THERMOKARST ON EARTH, MARS, AND TITAN. J.S. Kargel1 1Department of Hydrology and Water Resources, University of Arizona, Tucson, AZ 85721, USA ([email protected]). Introduction/Summary: MESSENGER has ac- quired stunning images of pitted, light-toned or varie- gated light/dark terrains located primarily on many of Mercury’s crater floors (Fig. 1) and on some ejecta blankets. Termed “hollows” by the imaging team, the pits have been described as unique in the Solar System. However, these terrains are geomorphologically simi- lar to some on Mars formed by sublimation of ice-rich permafrost (Fig. 2) and to lowland thermokarst on Earth formed by permafrost thaw; to “swiss cheese” terrain forming by sublimation of frozen CO2 at the Martian South Pole (Fig. 3); and to terrain at Titan’s poles thought to be hydrocarbon thermokarst (Fig. 4). Mercury lacks eolian processes that could erode the pits, and the pits do not possess volcanic characteris- tics. The most plausible explanation for Mercury’s hollows is terrain degradation involving melting or sublimation of heterogeneous chalcogenide and sul- fosalt mineral assemblages. Adapting the term ther- mokarst, I refer to these Mercurian features as pyro- thermokarst; the etymological redundancy distin- guishes the conditions and mineral agents from the ice- related features on Earth and Mars, though some of the physical processes may be similar. Working Hypothesis: Whereas ice has been long suspected and recently was discovered in permanently shadowed craters of Mercury’s polar regions, the hol- lows occur down to the equator, where neither ice nor sulfur is plausible. -
“Mineral Extraction in a Plurinational State: Commodification and Resource Governance in the Uyuni Salt Flat in Bolivia”
“Mineral Extraction in a Plurinational State: Commodification and Resource Governance in the Uyuni salt flat in Bolivia” Maria Daniela Sánchez-López 2017 A thesis submitted for the degree of Doctor of Philosophy to the University of East Anglia School of International Development This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution ABSTRACT The Uyuni salt flat (Salar de Uyuni) is located in the Bolivian high Andean plateau, is considered to be the largest salt flat on earth and a natural wonder. Concentrated in its brines, is the largest lithium deposit in the world, along with important reserves of potassium, magnesium and ulexite, collectively known as ‘evaporite resources’. Over the past 40 years, this landscape has been commodified and radically transformed in a continuous process of mining capitalist expansion. What is unfolding in the case of the Uyuni salt flat, however, is not just an economically- driven process of capitalist expansion, but also a transformation of the landscape linked to the value and symbolic meanings attached to the salt flat in an ongoing process of the neoliberalisation of nature. This thesis seeks to examine how social relations in terms of the material, discursive and cultural dynamics of evaporite mining shape and are shaped by governance frameworks. Based on a qualitative exploration, the research has three main objectives: i) to examine how and under what conditions the Uyuni salt flat has been commodified over the past 40 years (both under a neoliberal and post-neoliberal regime); ii) to analyse how lithium has exacerbated the territorial disputes and resource conflicts at local, departmental and national levels; and iii) to evaluate how and why territory and territoriality emerge as key elements within the process of commodification.
