  • Optimizing Flotation Circuit Recovery by Effective Stage

    Optimizing Flotation Circuit Recovery by Effective Stage

    Some of the main factors affecting the efficiency of the flotation circuit are the pulp chemical conditions (chemical reagent concentration, pH, aeration), physical conditions in the cell (mixing, supply and distribution of air, pulp level), and arrangement (size of the cells in …

  • Effect of Turbulence in Fine Bubbles Flotation

    Effect of Turbulence in Fine Bubbles Flotation

    Dec 06, 2017 flotation cell. As agitation rate increases the turbulence within the flotation cell increases, and consequently so does the flotation rate. From equation 4, Up and Ub are proportional to ε. As Up and Ub increase, the number of bubble-particle collisions increases (equation 3), raising the probability of collision and therefore the flotation rate.

  • A Brief Review of Pulp and Froth Rheology in Mineral Flotation

    A Brief Review of Pulp and Froth Rheology in Mineral Flotation

    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].

    There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells. The flotation columns are used for finer minerals and typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m 3. This is ...
