Slags are composed of iron-enriched minerals (fayalite, wüstite, hematite and goethite), while quartz, calcite and phyllosilicates are the main component of sediments. Geochemical results confirm the low capacity of thesé slags as a significant source of heavy metals to the environmentspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Oka riverSlagsSedimentsMineralogyHeavy metalsjournal articleopen access
