    Although single-stage (rougher) flotation is the conventional method of coal cleaning, there are a number of alternative circuits in use employing more than a single cell-bank for each feed-stream. One approach is the use of two cell banks for treating a pre-classified feed, i.e., coarse- and fine-coal feeds from a water-only cyclone.

    Feb 06, 2019· What are Flotation Cells? Flotation cells are used to separate minerals in a liquid solid suspension of desired and undesired materials. The desired solids are separated by making them hydrophobic, so they will attach to air bubbles that are created with either air injection or agitation along with a reagent. These solids flow over into a launder for capturing. The sinking solids are removed …
