Selenium (Se) and Tellurium (Te) are scarce (semi)metallic elements usually recovered as by-products of the chemical extraction of other metals. The proposal will exploit close relationships between these elements and organic materials to target additional resources, and extract resources in a more sustainable, environmentally sensitive manner.Se/Te are most concentrated in rocks containing organic matter (e.g. coals, carbon-rich shales, sandstones containing oil residues or coaly matter). We also know that microbial (bacterial) activity can concentrate Se/Te. We seek to use that knowledge to predict previously unrecognized concentrations of Se/Te by study of metal sulfide ores which are known to have been formed by microbial sulfate reduction, on the basis that these microbes could have also engendered Se/Te concentration. More significantly, we will try to advance our knowledge of how microbes interact with Se/Te in rocks and soil, to develop a strategy for the microbial concentration of Se/Te on a valuable scale. To achieve this the project combines interdisciplinary expertise on Se/Te from geology, soil science, chemistry and microbiology.The catalyst stage involves data gathering, and pilot sampling from two field sites, one in SW Ireland where some of the most Se-rich soils in the world occur, and in Scotland where a gold mine and its environs have elevated levels of Te, and the Te needs to be exploited to ensure financial viability. We have the support of Scotgold Resources, who own the gold mine, and Stantec, an international company whose portfolio includes management of metal resources.

硒（SE）和泰瑞尔（TE）是稀缺（半）金属元素，通常是作为其他金属化学提取的副产品回收的。该提案将利用这些元素和有机材料之间的密切关系来针对其他资源，并以更可持续的环境敏感的方式提取资源。Se/te最集中于含有有机物的岩石（例如煤，富含碳富含碳的页岩，含油或煤层的砂岩））。我们还知道，微生物（细菌）活性可以集中SE/TE。我们试图利用该知识来通过研究金属硫化物矿石来预测先前未识别的SE/TE浓度，而金属硫化物矿石已被微生物硫酸盐减少形成，因为这些微生物也可能导致SE/TE浓度。更重要的是，我们将尝试促进我们对微生物在岩石和土壤中如何与SE/TE相互作用的知识，以制定一种在有价值的规模上的微生物浓度的策略。为了实现这一目标，该项目结合了地质，土壤科学，化学和微生物学的SE/TE跨学科专业知识。催化剂阶段涉及数据收集，并从两个野外地点进行了抽样，一个在SW爱尔兰，其中一个在世界上最富裕的土壤中，在苏格兰有一些最富裕的土壤，以及在苏格兰发生了一项金矿及其环境，并确保了TE的级别，并且可以提高到TE的高度阶段。我们得到了拥有黄金矿的Scotgold Resources的支持，Scotgold Resources和Stantec是一家国际公司，其投资组合包括金属资源的管理。
