Flotation tailings Flotation is the concentration process commonly used in the mineral processing of copper sulfide ores. The ore is finely ground and the sulfides are separated from the gangue material. This process generates large amount of tailings, containing the gangue minerals and part of the sulfides (mainly pyrite). The tai­

waste generated during flotation is called tailings, which are discharged to the tailings impoundment structures. Tailings commonly contain sulfide minerals, e.g. pyrite (FeS2) and arsenopyrite (FeAsS), which weather when tailings are exposed to the air and oxygen. This can result in the liberation of arsenic and strong acid (i.e.
