12 p, 1.2 MB Dissolution of minor sulphides present in a pyritic sludge at pH 3 and 25º C / Cama Robert, Jordi (Consejo Superior de Investigaciones Científicas (Espanya). Institut de Ciències de la Terra Jaume Almera) ; Acero Salazar, Patricia (Consejo Superior de Investigaciones Científicas (Espanya). Institut de Ciències de la Terra Jaume Almera) ; Acero, P.
The steady-state dissolution rates of galena, sphalerite and chalcopyrite at pH 3 under oxygen saturated atmosphere and at 25ºC are obtained by means of non-stirred flow-through experiments. These dissolution rates are compared with those estimated by dissolving pyritic sludge from the Aznalcollar mining tailings composed of pyrite and minor sulphides galena, sphalerite and chalcopyrite.

9 p, 876.8 KB Chalcopyrite dissolution rate law from pH 1 to 3 / Acero Salazar, Patricia (Universidad de Zaragoza. Area de Petrología y Geoquímica) ; Cama Robert, Jordi (Consejo Superior de Investigaciones Científicas (Espanya).

Chalcopyrite dissolution kinetics in the pH range of 1 to 3 were studied by means of long-term flow-through experiments to obtain a dissolution rate law which can be coupled with reactive transport models to forecast Acid Rock Drainage. [...]
