Governance of strategic minerals in Latin America: the case of Lithium

The objectives of this report are twofold: The first is to provide an integrated overview of the governance of strategic minerals in the Latin American and Caribbean region, focused on sharing the economic-resource rent. The second objective is to provide a context for the policy proposal of the Chilean National Lithium Commission (NLC. The collected data, and information, on the various fiscal regimes can be used as a reference for further research. The objectives in this report are met by analyzing distinct aspects of strategic mineral governance, in three different parts. The lithium-industry serves as a case study for this report, as an example of a strategic mineral.

The Jurisprudence of the World Trade Organization 2014

In 2014, the Dispute Settlement Body (DSB) of the World Trade Organization (WTO) adopted seven panel reports and six Appellate Body rulings. Two of the cases relate to anti-dumping measures. Three cases, comprising five complaints, are of particular interest and these are summarized and discussed below. China – Rare Earths further refines the relationship between protocols of accession and the general provisions of WTO agreements, in particular the exceptions of Article XX GATT. Recourse to that provision is no longer excluded but depends on a careful case-by-case analysis. While China failed to comply with the conditions for export restrictions, the case reiterates the problem of insufficiently developed disciplines on export restrictions on strategic minerals and other commodities in WTO law. EC – Seals Products is a landmark case for two reasons. Firstly, it limits the application of the Agreement on Technical Barriers to Trade (TBT Agreement) resulting henceforth in a narrow reading of technical regulations. Normative rules prescribing conditions for importation are to be dealt with under the rules of the General Agreement on Tariffs and Trade (GATT) instead. Secondly, the ruling permits recourse to public morals in justifying import restrictions essentially on the basis of process and production methods (PPMs). Meanwhile, the more detailed implications for extraterritorial application of such rules and for the concept of PPMs remain open as these key issues were not raised by the parties to the case. Peru – Agricultural Products adds to the interpretation of the Agreement on Agriculture (AoA), but most importantly, it confirms the existing segregation of WTO law and the law of free trade agreements. The case is of particular importance for Switzerland in its relations with the European Union (EU). The case raises, but does not fully answer, the question whether in a bilateral agreement, Switzerland or the EU can, as a matter of WTO law, lawfully waive their right of lodging complaints against each other under WTO law within the scope of their bilateral agreement, for example the Agreement on Agriculture where such a clause exists.

África Austral: Los minerales como recurso estratégico para los intereses de Estados Unidos y China, período 2000-2010

La región de África Austral emerge como un nuevo escenario geopolítico complejo, en el que la lucha por la adquisición de los derechos de exploración, extracción y distribución de minerales estratégicos ha intensificado la presencia del número de actores estratégicos en esta zona. En este sentido, es interesante analizar el juego de poder que se desarrolla entre Estados Unidos y China con el fin de neutralizar la debilidad estratégica que representa la carencia de estos recursos naturales, esenciales para el desarrollo de sus industrias, así como también la oportunidad que representan como mecanismo para ampliar las esferas de influencia extra continental. Así pues, la presente investigación analiza a partir de la explotación de los minerales como recursos estratégicos, los efectos de la geoestrategia reciente de estos dos jugadores activos del sistema internacional contemporáneo en la relación con los Estados que conforman la región meridional del continente africano, durante el periodo 2000-2010.

Minerals and vitamin B9 in dried plants vs. infusions: assessing absorption dynamics of minerals by membrane dialysis tandem in vitro digestion

Vitamins and mineral elements are among the most important phytochemicals due to their important role in the maintenance of human health. Despite these components had already been studied in different plant species, their full characterization in several wild species is still scarce. In addition, the knowledge regarding the in vivo effects of phytochemicals, particularly their bioaccessibility, is still scarce. Accordingly, a membrane dialysis process was used to simulate gastrointestinal conditions in order to assess the potential bioaccessibility of mineral elements in different preparations of Achillea millefolium (yarrow), Laurus nobilis (laurel) and Taraxacum sect. Ruderalia (dandelion). The retention/passage dynamics was evaluated using a cellulose membrane with 34 mm pore. Dandelion showed the highest levels of all studied mineral elements (except zinc) independently of the used formulations (dried plant or infusion), but yarrow was the only species yielding minerals after the dialysis step, either in dried form, or as infusion. In fact, the ability of each evaluated element to cross the dialysis membrane showed significant differences, being also highly dependent on the plant species. Regarding the potential use of these plants as complementary vitamin B9 sources, the detected values were much lower in the infusions, most likely due to the thermolability effect.

Raman spectroscopy of the molybdate minerals chillagite (tungsteinian wulfenite-I4), stolzite, scheelite, wolframite and wulfenite

Raman spectra of chillagite, wulfenite, stolzite, scheelite and wolframite were obtained at 298 and 77 K using a Raman microprobe in combination with a thermal stage. Chillagite is a solid solution of wulfenite and stolzite. The spectra of these molybdate minerals are orientation dependent. The band at 695 cm-1 is interpreted as an antisymmetric bridging mode associated with the tungstate chain. The bands at 790 and 881 cm-1 are associated with the antisymmetric and symmetric Ag modes of terminal WO2 whereas the origin of the 806 cm-1 band remains unclear. The 4(Eg) band was absent for scheelite. The bands at 353 and 401 cm-1 are assigned as either deformation modes or as r(Bg) and (Ag) modes of terminal WO2. The band at 462 cm-1 has an equivalent band in the infrared at 455 cm-1 assigned as as(Au) of the (W2O4)n chain. The band at 508 cm-1 is assigned as sym(Bg) of the (W2O4)n chain.

An infrared spectroscopic study of the some Autunite minerals

A series of selected autunites with phosphate as the anion have been studied using infrared spectroscopy. Each autunite mineral has its own characteristic spectrum. The spectra for different autunites with the same composition are different. It is proposed that this difference is due to the structure of water and hydrated cations in the interlayer region between the uranyl phosphate sheets. This structure is different for different autunites. The position of the water hydroxyl stretching bands is related to the strength of the hydrogen bonds as determined by hydrogen bond distance. The highly ordered structure of water is also observed in the water HOH bending modes where a high wavenumber bands are observed. The phosphate and uranyl stretching vibrations overlap and are obtained by curve resolution.
