    Thus lack of selectivity, as well as composite particle flotation, is seen to be responsible for downgrading of lead third cleaner concentrates. In addition, the QEM*SEM technique has shown that the distribution of galena intergrowth in lead first cleaner tailings is spread over most composite classes, more akin to regrind/retreat particles than to lead primary rougher tail particles.

    The Flotation Process. In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.
