Flotation separation
Flotation is a mineral separation process, which takes place in a water-mineral slurry. The ore material usually be grinding to cut separation by ball mill before flotation separation and then put into flotaion machine by pumps . T he surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective reagents. The hydrophobic particles become attached to air bubbles that are introduced into the pulp and are carried to a froth layer above the slurry thereby being separated from the hydrophilic (wetted) particles. In addition to the reagents added, the flotation process depends on two main parameters. Retention time needed for the separation process to occur determines the volume and number of flotation cells required. Agitation and aeration needed for optimum flotation conditions, determine the type of flotation mechanism and the power input required.
