Indium recovery is based primarily on zinc extraction from sphalerite, the prototype of so-called tetrahedral sulphides, wherein metal ions fill half of the available tetrahedral sites within the cubic closest packing of sulphur anions, leaving interstices accessible for further in-filling. Ascertaining the tendency towards the establishment of In-In interactions through an x-ray absorption spectroscopy approach would efficiently contribute to understanding the behavior of indium in the carrier mineral. The successful results of applying such a near-edge absorption (XANES) study at In L3-edge to samples collected at the Lagoa Salgada polymetallic orebody in the Iberian Pyrite Belt (IPB) are described and the crystal chemistry of indium is re-evaluated, disclosing a potential clue for the metal binding state in polymetallic sulphides.<\/jats:p>","DOI":"10.3390\/min2040426","type":"journal-article","created":{"date-parts":[[2012,11,6]],"date-time":"2012-11-06T11:18:13Z","timestamp":1352200693000},"page":"426-434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Indium-Carrier Minerals in Polymetallic Sulphide Ore Deposits: A Crystal Chemical Insight into an Indium Binding State Supported by X-ray Absorption Spectroscopy Data"],"prefix":"10.3390","volume":"2","author":[{"given":"Maria-Ondina","family":"Figueiredo","sequence":"first","affiliation":[{"name":"Department of Materials Science, Faculty of Sciences and Technology, New University of Lisbon, Campus da Caparica, 2829-516 Caparica, Portugal"},{"name":"National Laboratory for Energy and Geology (LNEG), Unit of Mineral Resources and Geophysics, Apartado 7586, 2610-999 Amadora, Portugal"}]},{"given":"Teresa Pereira da","family":"Silva","sequence":"additional","affiliation":[{"name":"National Laboratory for Energy and Geology (LNEG), Unit of Mineral Resources and Geophysics, Apartado 7586, 2610-999 Amadora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6338-8845","authenticated-orcid":false,"given":"Daniel de","family":"Oliveira","sequence":"additional","affiliation":[{"name":"National Laboratory for Energy and Geology (LNEG), Unit of Mineral Resources and Geophysics, Apartado 7586, 2610-999 Amadora, Portugal"}]},{"given":"Diogo","family":"Rosa","sequence":"additional","affiliation":[{"name":"Department of Petrology and Economic Geology, Nationale Geologiske Unders\u00f8gelser for Danmark og Gr\u00f8nland (GEUS), \u00d8ster Voldgade 10, 1350 K\u00f8benhavn K, Denmark"}]}],"member":"1968","published-online":{"date-parts":[[2012,11,6]]},"reference":[{"key":"ref_1","unstructured":"Figueiredo, M.O., Silva, T.P., de Oliveira, D.P.S., and Rosa, D.R.N.
