2007-6-1 · The study was conducted at four mine tailings in the Cartagena-La Unión Mining District (): “Belleza”, “El Gorguel”, “Lirio” and “Brunita”.A complete substrate characterization for the four sites was carried out by Conesa, 2005, Conesa et al., 2006 ().This characterization showed two different types of tailings in relation to pH: extremely acid, “Belleza” and “Brunita ...

Heavy metal accumulation and tolerance in plants from

Some edaphic factors were investigated, including heavy metal concentrations, in three mine tailings from a semiarid mining zone in Southeast Spain. High total metal concentrations were found: 5000-8000 mg/kg for lead and 7600-12300 mg/kg for zinc. Two of these mine tailings had pH values between 6 and 7, while the other was acidic, with a pH ...

Environmental Risks of Mining
