(ELSEVIER, 2003-10)This work presents preliminary results of a study to determine the technical feasibility of heap bioleaching of copper sulfides in a mixed ore that had previously undergone a chemical leach to recover the copper from the ...
-
(Elsevier, 2008)The catalytic influence of Sulfolobus metallicus in the bioleaching of chalcopyrite at 70 degrees C and pH 1.5 was studied in shake flask experiments. Leaching was conducted in an iron-free basal medium with a -80 #+ 120 ...

Estudio experimental de la cinética de corrosión del hormigón mediante acidithiobacillus thiooxidans (Universidad de Chile, 2017)Este trabajo se realizó en el Laboratorio de Biohidrometalurgia del Departamento de Ingeniería Química y Biotecnología de la Facultad de Ciencias Físicas y Matemáticas de la Universidad de Chile. El objetivo principal de ...
-
(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) ...

(ELSEVIER, 2008-06)Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans are two of the most important bacteria in heap bioleaching processes of copper sulphide at common operating temperatures (18-24 degrees C). In this paper, both ...
