Attachment of Acidithiobacillus ferrooxidans and Leptospirillum ferriphilum cultured under varying conditions to pyrite, chalcopyrite, low-grade ore and quartz in a packed column reactor

Author: Africa, Cindy-Jade ; van Hille, Robert P ; Harrison, Susan T L Date: 2012 The attachment of Acidithiobacillus ferrooxidans and Leptospirillum ferriphilum spp. grown on ferrous medium or adapted to a pyrite mineral concentrate to four mineral substrata, namely, chalcopyrite and pyrite concentrates, a low-grade ...

In situ investigation and visualisation of microbial attachment and colonisation in a heap bioleach environment: the novel biofilm reactor

Author: Africa, Cindy-Jade ; Harrison, Susan T L ; Becker, Megan ; van Hille, Robert P Date: 2010 In this paper, the development of a novel means of investigating the attachment and subsequent biofilm formation of mineral bioleaching micro-organisms to mineral surfaces in situ is described. The protocol was developed to investigate the ... Read more
Investigation and in situ visualisation of interfacial interactions of thermophilic microorganisms with metal-sulphides in a simulated heap environment

Author: Africa, Cindy-Jade ; van Hille, Robert P ; Sand, Wolfgang ; Harrison, Susan T L Date: 2013 This study sought to provide a better understanding of the dynamics of microbial-metal sulphide interfacial processes relevant to heap bioleaching. Attachment and subsequent biofilm formation by Metallosphaera hakonensis (M. hakonensis) on ... Read more
Investigation of microbial metal-sulfide interfacial environments under mineral bioleach simulated conditions

Author: Africa, Cindy-Jade Date: 2017 This research pertains to bioleaching of copper containing ores with particular reference to the copper sulfide mineral chalcopyrite (CuFeS2). While it is focused on heap bioleaching, it has applications to stirred tank bioleaching operations. ... Read more
Microbial attachment to sulfide minerals in a bioleach environment

Author: Africa, Cindy-Jade Date: 2009 This research pertains to bioleaching of copper containing ores with particular reference to the copper sulfide mineral chalcopyrite (CuFeS₂). While it is focused on heap bioleaching, it has applications to stirred tank bioleaching operations. ... Read more
