    • Dissolved pollutant transport in tailings ponds 
      Wiertz Frisque, Jacques; Marinkovic, F. A. (SPRINGER, 2005-06)
      Water and dissolved ion transport in mineral tailings was studied at laboratory scale with three different tailings samples. Percolation rate, determined in column experiments, depends mainly on the granulometric distribution ...
    • Mechanism of pyrite catalysis of As(III) oxidation in bioleaching solutions at 30 degrees C and 70 degrees C 
      Wiertz Frisque, Jacques; Mateo, Magda; Escobar Miguel, Blanca (ELSEVIER, 2006-09)
      Arsenic, present as impurity in many sulfide ores, dissolves during the bioleaching process and the resulting high As(Ill) concentration can inhibit bacterial activity, compromising the whole process. Oxidation of As(III) ...
