Abstract: The present work investigates the adsorption and mobility (desorption) of As(III) and As(V) on an oxisol, and its main mineral constituents, as part of a broader project aimed at selecting a soil liner to be used in tailings dams at a sulfidic gold ore plant. Emphasis was given to a quantitative comparison of As mobility-here assessed by the amount of As leached from the loaded samples-under different experimental conditions. From among the soil constituents, goethite was the most efficient adsorbent with rega…
