    The froth of copper-rich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners.

    Froth flotation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SX-EW) plant or smelted. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals.

    In general froth flotation is not used to concentrate copper oxide ores, as oxide minerals are not responsive to the froth flotation chemicals or process (ie; they do not bind to the kerosene-based chemicals). Copper oxide ores have occasionally been treated via froth floatation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin.
