The Jameson Cell concept was developed by Graeme Jameson of the University of Newcastle and the technology was developed for commercial application by Mount Isa Mines Limited (MIM). Laboratory investigations highlighted significant differences between Jameson Cells and other flotation technologies. The installation of Jameson Cells in MIM's copper concentrator in 2002 has allowed a detailed investigation of Jameson Cell fundamentals to be conducted within a mineral flotation system. On line measurements, together with non-invasive measurement techniques for detailing operation within the primary contacting zone (the downcomer) and the secondary contacting zone (the tank) has allowed a detailed review of Jameson Cell operation to be conducted. This paper shows that assumptions based on mechanical flotation cells, conventional and non-conventional flotation columns and even pneumatic flotation devices do not necessarily transfer to the Jameson Cell. The effects of feed flow rate, feed percent solids, froth depth and aeration rate are discussed in relation to the Jameson Cell downcomer residence time. Aeration effects within the Jameson Cell tank are also discussed. (C) 2003 Elsevier Ltd. All rights reserved.
