RESUMOFoi desenvolvido um método simples e rápido para separação e purificação simultânea de Cu, Zn e Mo e a medição exata e precisa das suas composições isotópicas em amostras geológicas utilizando espectrometria de massa com plasma indutivamente acoplado e sistema multicoletor (MC-ICPMS). O método envolve o uso de uma única coluna cromatográfica, preenchida com a resina de troca aniônica AG-MP-1 para separação e purificação desses três elementos a partir da sua matriz complexa. O método Sample-Standard-Bracketing (SSB) combinado à adição de padrão interno foi usado para a correção exata e precisa do viés de massa instrumental nas medições das razões isotópicas de Cu, Zn e Mo. O método foi aplicado a diferentes materiais geológicos, como granodiorito (GSP 2-USGS), calcário (JLS-1, Japão), sedimentos do Rio Buffalo (NIST SRM -8704) e sedimentos da Bacia Amazônica. A precisão média para essas amostras foram: 0,08 ‰ para δ δ65/63 Cu; 0,05 ‰ para δ 66/67 Zn e 0,04 ‰ para δ 98/95 Mo. A principal vantagem é que o método proposto é simples e rápido, realiza a recuperação quantitativa dos elementos de diferentes massas atômicas e em concentrações muito baixas, principalmente para Mo. Em conjunto, a correção do viés de massa instrumental a partir de um método mais simples, produziu resultados consistentes aos outros métodos atualmente publicados. A comparação entre as composições isotópicas de Cu e Mo obtidas para granodiorito com os dados relatados na literatura, demonstra que o método mais simples e multielementar, desenvolvido neste estudo, estão dentro dos limites de precisão requeridas e pode ser utilizado adequadamente como ferramenta multi-proxy em geoquímica de isótopos. Palavras-chaves: isótopos de Zn, Cu e Mo, MC-ICPMS, cromatografia de troca iônica, material geológico ABSTRACT A simple and quick method for simultaneous purification of Cu, Zn and Mo and accurate and precise measurement of their isotopic composition in geological samples using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has been developed. The method involves the use of a single chromatographic column filled with the anion exchange resin AG-MP-1 for complex matrix removal and further purification of these three elements. The external standard-sample-standard bracketing (SSB) procedure combined to internal standard addition was used for accurate mass bias correction and precise Cu, Zn and Mo isotopic ratio measurements. The method was applied to different geological materials, as granodiorite (GSP 2-USGS), limestone (JLS-1, Japan), Buffalo River Sediments (NIST SRM -8704) and sediments from Amazon River Basin. The mean precision for these samples was: 0.08 ‰ for δ 65/63 Cu; 0.05 ‰ for δ 66/67 Zn and 0.04 ‰ for δ 98/95 Mo. The main advantage is that the proposed method is simple and rapid, and carries out the quantitative recovery of elements of different atomic

“…They conclude that "tracing environmental contamination 'remains challenging'", though the slags showed Ni-enrichments and fractionation compared to soil samples. Skierszkan et al (2016) looked at both Mo and Zn isotopes in mining waste rock and drainage in Peru. Wiederhold (2015) comprehensively reviewed the use of metal (stable) isotope fractionation in natural systems.…”

This paper summarizes international state-of-the-art applications and opportunities for employing and deploying hydrological, geochemical, and isotopic tools in an integrated manner for investigations of mining operations. It is intended to aid formulation of more integrated approaches for evaluating the overall sustainability of mining projects. The focus is particularly on mine waters, including: environmental water sources, mine water dynamics, and as a source and vector for pollution in the wider environment. The guidance is generic to mining projects and not just reflective of a particular extraction (e.g. coal, metalliferous, uranium) industry. A mine life cycle perspective has been adopted to highlight the potential for more integrated investigations at each stage of a mining operation. Three types of mines have been considered: new (i.e. those in the planning stage), active (i.e. working mines), and historical mines (i.e. inactive and abandoned mines). The practical usage of geochemical analyses and isotopic studies described here emphasise characterisation, dynamics, and process understanding for water quality considerations in tandem with water resource and environmental impact implications. Both environmental (i.e. ambient) and applied (i.e. injected) tracers are considered. This guide is written for scientists (including isotope specialists) who have limited or no mine water experience, environmental managers, planners, consultants, and regulators with key interests in planned, active, and legacy mining projects.

Abstract:Molybdenum is an essential element for life, with growing production due to a constantly expanding variety of industrial applications. The potentially harmful effects of Mo on the environment, and on human and ecosystem health, require knowledge of Mo behavior in mining-affected environments. Mo is usually present in trace amounts in ore deposits, but mining exploitation can lead to wastes with very high Mo concentrations (up to 4000 mg/kg Mo for tailings), as well as soil, sediments and water contamination in surrounding areas. In mine wastes, molybdenum is liberated from sulfide mineral oxidation and can be sorbed onto secondary Fe(III)-minerals surfaces (jarosite, schwertmannite, ferrihydrite) at moderately acidic waters, or taken up in secondary minerals such as powellite and wulfenite at neutral to alkaline pH. To date, no Mo-metabolising bacteria have been isolated from mine wastes. However, laboratory and in-situ experiments in other types of contaminated land have suggested that several Mo-reducing and -oxidising bacteria may be involved in the cycling of Mo in and from mine wastes, with good potential for bioremediation. Overall, a general lack of data is highlighted, emphasizing the need for further research on the contamination, geochemistry, bio-availability and microbial cycling of Mo in mining-affected environments to improve environmental management and remediation actions.
