Biooxidation kinetics of Leptospirillum ferriphilum under heap bioleach conditions

Author: Ojumu, T V ; Harrison, S T L ; Hansford, G S ; Petersen, J Date: 2008 Although the kinetics of biological oxidation of ferrous to ferric iron–the key step in any bioleaching process–have been studied for a variety of organisms, the focus has always been on conditions typical of tank-bioleaching. In heaps, ... Read more
The kinetics of ferrous-iron oxidation by Leptospirillum ferriphilum in continuous culture: the effect of pH

Author: Ojumu, T V ; Petersen, J Date: 2011 The kinetics of ferrous ion oxidation by Leptospirillum ferriphilum were studied in continuous culture with a focus on the effect of solution pH (pH 0.8–2.0), assuming that the effect of pH on cell metabolism can be independently studied of ... Read more
The kinetics of ferrous-iron oxidation by Leptospirillum ferriphilum in continuous culture: the effect of temperature

Author: Ojumu, T V ; Hansford, G S ; Petersen, J Date: 2009 A typical bioleach heap is characterized by wide variation of temperature across the heap bed, leading to oxidation of target minerals occurring at different rates. Previous studies on the effect of temperature on the microbial oxidation of ... Read more
A review of rate equations proposed for microbial ferrous-iron oxidation with a view to application to heap bioleaching

Author: Ojumu, T V ; Petersen, J ; Searby, G E ; Hansford, G S Date: 2006 In view of the fact that the microbial oxidation of ferrous iron to the ferric form is an essential sub-process in the bioleaching of sulphide minerals, the development of a comprehensive rate equation for this sub-process is critical. Such ... Read more
