The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the College of Newcastle (Australia) and developed along with Mount Isa Mines Restricted (“MIM”, a subsidiary of MIM Holdings Restricted and now a part of the Glencore group of corporations).[1]

Introduction[edit]
The Cell was initially developed as a lower-cost different to standard column flotation cells for recovering superb particles, and was first used within the Mount Isa lead–zinc concentrator in 1988.[6] Since then, use of the expertise has unfold to incorporate coal flotation, base and treasured metallic flotation, potash flotation, oil sands flotation, molybdenum flotation, graphite flotation and cleansing solvent extraction liquors.[7] Xstrata Know-how, Glencore Xstrata’s expertise advertising arm, listed 328 Jameson Cell installations in Could 2013.[7] Cells have been put in by 94 corporations in 27 nations.[7] At present, the expertise is the usual within the Australian Coal Trade[8] the place properly over 100 Cells have been put in to get well coal fines.[9][10] It’s primarily utilized in metals purposes to unravel remaining grade and capability points from typical cell cleaner circuits.[5] It has discovered a distinct segment in reworking conventional circuit designs the place its inclusion permits cleaner circuits to be designed with fewer cells in a smaller footprint, whereas attaining cleaner and/or greater grade concentrates.[5] It has additionally made attainable the restoration of beforehand discarded superb supplies, similar to coal[11] and phosphate fines,[12] thereby rising the effectivity and lengthening the lifetime of the world’s non-renewable pure assets.
Working ideas[edit]
The Cell has no shifting components and no requirement for compressed air or sparging mechanisms.[21] This leads to decrease energy consumption than the equal mechanical or column flotation cells.[4] Upkeep prices are additionally decrease as a result of the one sporting half is the slurry lens used to create the jet within the downcomer.[4]
Historical past[edit]
The Mark IV Cell design was launched in 2009. It included the next enhancements:
Present purposes[edit] – “zinc jameson”
Legend Worldwide Holdings Included (“Legend”) owns main phosphate deposits that common 20–60% particles lower than 20 μm that comprise as much as 50% of the phosphate.[12] This makes the standard phosphate focus observe uneconomic for these deposits.[12] In response, Legend developed a course of primarily based on utilizing the Jameson Cell in a rougher-scavenger-cleaner configuration to get well no less than 80% of the phosphate at a grade of no less than 32% P2>O5 from a feed with a particle dimension distribution of as much as 80% lower than 20 μm.[12]
Benefits[edit]
The Jameson Cell reportedly has the next benefits:
