Copper extraction Wikipedia

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 (i.e. they do not bind to the kerosenebased chemicals). Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the
