    Dec 10, 2016 In this work, a composite central design with five levels and four variables was employed to model and optimize the batch flotation kinetic process in a cyclonic microbubble flotation column (FCMC). 30 sets of batch flotation rate tests were executed at different conditions of pulp concentration (X 1), frother dosage (X 2), flow rate of circulation pulp (X 3) and froth depth (X 4)

    column flotation and its segregation was desirable. However, we were not able to isolate Krofta rejects from other reject streams. Thus, column flotation tests were performed with a blend of Krofta and Cleanpac heavy rejects. Rejects Column flotation at six-minute retention time removed 70–80% of macrostickies and wax from the process rejects

Flotation is used for fine coal beneficiation, where operating parameters must be optimised for individual coal (Kaylani et al., 2005). A flotation column is used in the cleaning stages of flotation circuits due to a better selectivity in relation to conventional

    Jameson cell - Wikipedia

    The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
