  • Flotation Cell an overview | ScienceDirect Topics

    After conditioning with suitable reagents, the pulp is fed to a single aerating unit arranged in the vertical pipe above the flotation cell. The aerated pulp flows through the central pipe to the slurry distributor ring located at the bottom of the cell where it is vertically deflected upward through high wear-resistant ceramic nozzles. A special aerator, a self-aspirating unit, plays an

    The pulp suspension is pumped through the multi-injectors into the flotation cells. These newly developed multi-injectors of the next generation minimize the pressure drop in the injector, hence reducing the energy demand. Inside the patented injectors, the pressure energy is used to suck air into the feed stock. The right amount of air, together with the optimized injector geometry lead to

  • A Brief Review of Pulp and Froth Rheology in Mineral

    For non-Newtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. In several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s −1 or 160 s −1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].

  • Considering the effect of pulp chemistry during flotation

    The effect of changing the pulp factors on the froth bubble size was investigated by capturing side view images of the froth obtained in a batch flotation cell as each pulp factor was changed. This study has shown that careful control of the pulp chemistry, namely increasing IS, increasing pH, decreasing DO and decreasing Eh, resulted in improved froth stability. The Eh was found to be

    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

    22/03/2010· The gas hold-up depends on the amount of air added to the flotation cell and is a strong function of pulp viscosity. Through the proven design of the flotation tank and mechanism, gas hold-up in Outotec flotation cells is typically limited to between 5 per cent and 15 per cent of the total pulp volume, thereby maximising the cell volume and residence time.
