    In conventional flash flotation, a SkimAir cell is operated as a standalone cell in a single stage process. The single stage process can be recovery- or grade-driven. In a two-stage process, the SkimAir is used as a rougher unit to produce a lower grade concentrate at high recovery, and an Outotec TankCell® is used as a cleaner to

    What Ore is Suitable for Flotation. The largest class of ores treated by the flotation process consists of those containing the sulphide minerals of copper ; these sometimes contain native copper and also gold and silver, all of which can generally be floated with the sulphide minerals in one concentrate.

    Aug 06, 2010· The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed; the cleaner, which generates the final concentrate; and the scavenger, which generates the final tailing, as shown in Fig. (1).This is a simple superstructure but is used here as an example.

    The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by ...

    The concentrate from the flotation section usually contains only 20 to 30% of solids as it leaves the cleaning machine and must be dewatered before being sent to the next department. The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% ...

  • Froth Flotation Process - Mineral Processing & Metallurgy

    A froth flotation process is used to concentrate copper ore. It is a two-stage process that involves one rougher stage and one cleaner stage. The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steady-state. The analytical profile of the entire flotation circuit is:

    The indispensable tool for Cu concentrate production is froth flotation (Fuerstenau, Jameson, & Yoon, 2007). This technique is used to upgrade an ore to a concentrate by selectively floating copper-containing minerals away from non-copper minerals. The principles of froth flotation are as follows:
