flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. the function of the rotor/stator is to make bubbles from the induced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise to the top as froth for concentration and collection.,brainwave flotation - andritz,brainwave flotation stabilizes the operation of all types of rougher, cleaner, and scavenger flotation cells. the result is more efficient operation and improved mineral recovery. brainwave is used to maintain the level in each of the flotation cells. by using its model-based predictive control algorithm, coupled with its unique integrating control
newer flotation cells are generally larger, with more efficient mixing and air dispersion. there are really two ways to improve profit on-site. one way is to focus on profit through cost savings and reducing operating costs. the second way is through producing more metal by improving operational efficiency and equipment availability.,kinetics of flotation. order of process, rate constant,function of k for different particles in the flotation cell, and thus eq. 6 can be equal to: dr r n dt f . (7) the ultimate recovery r∞, distribution of flotation rate constant f(k) and order of flotation kinetics n in eqs. 6 and 7 can be determined from the experimental data of r versus t.
