    17.10.2016· Flotation Circuits for Air-Lift and Pneumatic Cells. An air-lift machine can often be run as a rougher-cleaner cell, as in circuit No. 5 (Fig. 52), by taking a finished concentrate off the first few feet and returning the froth from the rest of the machine to the feed end. This method is also applicable to pneumatic cells, but its use is not common. As with mechanically agitated machines, careful control is

    12.08.2015· The UNDERFLOW is the pulp. When the pulp has had all the mineral extracted from it that the circuit was able to, and is discharged it is then called the flotation TAILINGS of the circuit. The flotation HEADS, the CONCENTRATE and the TAILINGS are the most important samples for the flotation operator that are taken. The assays from these will tell the operator the amount of valuable mineral coming in to the circuit. The amount that went out of the circuit.

  • Froth Flotation Circuit Design And Basic Testwork

    Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed, (directly related to ore grade). Depending on the specific mineral

    04.03.2005· The rougher flotation step is often followed by a scavenger flotation step that is applied to the rougher tailings. The objective is to recover any of the target minerals that were not recovered during the initial roughing stage. This might be achieved by changing the flotation conditions to make them more rigorous than the initial roughing, or there might be some secondary grinding to provide further

    Flotation system is based around a group of 6 float cells arranged in a circular tank, each individual cell fitted with impellers, air spargers and froth launders. Host of benefits in the design; better mixing in slurry applications, resulting in greater efficiency for reactions and a greater uniformity within the tank. This results in fast flotation kinetics and better recoveries over conventional systems.

  • Kinetics of flotation. Order of process, rate constant

    Traditionally, evaluation of batch flotation tests is based largely on a rougher recovery value achieved at a defined time. Since the cumulative recovery of a component in the concentrate is proportional to flotation time, the flotation process can be considered as a time-rate recovery process. Therefore, a mathematical flotation model that incorporates both the recovery and rate function can
