Hydrogeochemistry and distribution of potentially toxic elements in a metallogenic province – The Iberian Pyrite Belt, Portugal

Autor: Gomes Patricia, Valente Teresa, Costa Maria Rosário, Fonseca Rita, Costa Ana, Neves Orquídea, Moreno Filipa

Publikováno v: E3S Web of Conferences, Vol 98, p 01016 (2019)

Contamination by acid drainage is an environmental problem in mineralized regions, especially in the surroundings of sulphide mines. The water rock interaction process involves the oxidative dissolution of sulphides, naturally or by mining activity,

Hydrochemistry of pit lakes in the Portuguese sector of the Iberian Pyrite Belt

Autor: Gomes Patrícia, Valente Teresa, Cordeiro Mayara, Moreno Filipa

Publikováno v: E3S Web of Conferences, Vol 98, p 09007 (2019)

The Iberian Pyrite Belt (IPB) is a world-class metallogenic province with volcanogenic massive sulphide ore deposits. Most ore exploitation occurred since pre-Roman time, creating extensive galleries, wells, waste-dumps and pit lakes. These last stru

Thorium and Uranium distribution in a passive system for mine water treatment

Autor: Prudêncio Maria Isabel, Valente Teresa, Marques Rosa, Sequeira Braga Maria Amália, Pamplona Jorge

Publikováno v: E3S Web of Conferences, Vol 98, p 09023 (2019)

The abandoned Jales mining area is a sulphide-rich deposit (Northeast of Portugal). Acid mine drainage resulted from oxidation of sulphides is treated in a passive system with wetlands. The present work studies the thorium and uranium behaviour in th

Partitioning of potentially toxic elements among two colloidal fractions and relevance for their mobility in different water types

Autor: Moreno Filipa, Valente Teresa, Gomes Patrícia, Fonseca Rita, Costa Maria Rosário, Costa Ana

Publikováno v: E3S Web of Conferences, Vol 98, p 09020 (2019)

Potentially toxic elements are mobilized in aquatic systems in solution or bounded to colloids of different sizes, which may include nanometer particles. The present work studies the distribution of elements (Al, Fe, Zn, Mn, Co, Cd, Ni, Cu, and As) b
