The influence of applied potentials and temperature on the electrochemical response of Chalcopyrite in Bacterial Leaching

Author: Tshilombo, A F ; Petersen, J ; Dixon, D G Date: 2002 Electrochemical techniques were conducted to clarify the role of solution potential and temperature under a variety of experimental conditions similar to those found during the mesophilic and thermophilic biooxidation of chalcopyrite (CuFeS2). ...

Modelling zinc heap bioleaching

Author: Petersen, J ; Dixon, D G Date: 2007 A comprehensive modelling study of the HydroZinc™ heap bioleach process, using the HeapSim modelling tool, is described. The model was calibrated on the basis of a small number of column leach experiments and compared against pilot heap test ... Read more
Thermophilic Heap Leaching of a Chalcopyrite Concentrate

Author: Petersen, J ; Dixon, D G Date: 2002 Thermophiles have been shown to be the only micro-organisms to leach chalcopyrite successfully. Heap leaching may be a feasible alternative to conventional bio-reactors, providing a high temperature environment can be maintained within the ... Read more c b n d
