Bioleaching cobalt from sulphide ores | COG3 Consortium

Recently, members of the Acidophile Research Team at Bangor University carried out some bioleaching experiments which aimed to leach cobalt from the Captain sulfide ore (from New Brunswick, Canada). Sarah Smith, a geomicrobiologist at Bangor University and one of the collaborators in the COG3 project reports.

The aim was to compare the bioleaching rates of metals (primarily cobalt) from the ore at two different temperatures. To do this, two different mixed cultures were grown up (one containing bacteria that are happy at about 30°C, and another with bugs that prefer slightly higher temperatures). The cultures were then added to the bioreactors, along with the ore, and the bugs were left to work their magic!

Annual Science Advisory Board meeting | CoG3 Consortium

Dr Paul Schofield gives an account of the CoG3 project’s annual Science Advisory Board meeting, held on the 6 and 7 June 2016 at the Bangor Acidophile Research Team (BART) centre, Bangor University.

The overall purpose of our Science Advisory Board is to assess and advise upon the strategic direction of the team’s project, CoG3: Geology, Geochemistry and Geomicrobiology of Cobalt. It also ensures that all components of the project stay focused on their objectives and remain sufficiently integrated so that the entire project can deliver the desired impact.
