rougher flotation banks
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 losses Therefore they are generally larger in size and numbers Cleaner banks
