Flotation circuits are typically comprised of rougher scavenger and cleaner flotation banks rougher and scavenger banks are focused on recovery and thus provide maximum residence time rougher banks can be large with the number of cells being 5 or greater scavenger cells are the last line of defense for avoiding
Froth flotation depends on differences in surface properties between coal and shale air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10 the hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as
Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic importantly the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt
