Includes bibliographical references (leaves 69-75). Bioleaching has developed into a very important process for the recovery of valuable metals, particularly from low grade copper ores due to the ever increase in demand. A lag phase is present during the start-up phase of heap bioleach operations characterised by a low degree of microbial colonisation, a low ferrous iron oxidation rate and low microbial proliferation rates, ultimately resulting in a poor copper recovery rate. 2014-07-31T11:13:50Z 2014-07-31T11:13:50Z 2009 Master Thesis Masters MSc http://hdl.handle.net/11427/5388 eng application/pdf Centre for Bioprocess Engineering Research Faculty of Engineering and the Built Environment University of Cape Town |
