Optimizing Flotation Cells H ow a flotation cell works Flotation Cells Froth Flotation were developed to separate and recover high value Sulphide ores from low grade ore bodies The ore is crushed and milled at the concentrator in a process known as comminution where the mineral is in suspension in slurry
density is too low minerals are washed out of the cell before they have a chance to float If the density is too high the agitators will be unable to disperse enough air into the cell and the slurry will be difficult to keep in suspension Flotation agitators have three basic functions to keep sand in suspension to disperse air as discrete
